Aesi is strongest when you upgrade consistency before flash
This Aesi, Tyrant of Gyre Strait Commander deck guide focuses on landfall upgrades and budget swaps that make the deck smoother: 40 to 43 lands, 12 to 15 ramp pieces, enough cheap interaction, and finishers that convert extra lands into a real endgame. Upgrade cards that create multiple land drops or multiple landfall triggers before buying expensive splashy threats.
Aesi deck construction targets
Core cards and roles for the Aesi shell
Aesi, Tyrant of Gyre Strait
Commander and engine
Adds an extra land play and turns each land entering under your control into a card, so the list should maximize repeatable land drops rather than one-shot draw spells.
Tatyova, Benthic Druid
Backup engine
Keeps the deck functional when Aesi costs eight or ten mana. Keep this effect in most builds because it makes land-search spells into cards and life.
Azusa, Lost but Seeking
Premium extra land engine
The strongest Aesi upgrade when your land count is high. Azusa lets Aesi chains turn drawn lands into more cards immediately.
Dryad of the Ilysian Grove
Fixing and extra land
Adds another land drop while fixing awkward hands, making it better than many generic three-mana ramp cards in Aesi.
Lotus Cobra
Landfall mana burst
Turns fetch lands, Harrow effects, and Aesi draw turns into extra mana so you can keep casting spells instead of only drawing cards.
Tireless Provisioner
Budget-to-midrange resource engine
Creates Food or Treasure on landfall. Treasure is especially strong with Aesi because land drops can fund more ramp, protection, or a finisher in the same turn.
What Aesi is trying to do
Aesi is a landfall value commander, not just a generic Simic ramp commander. The commander gives an extra land play, then rewards every land entering under your control. The best Aesi upgrades either put lands onto the battlefield, let you play extra lands from hand, protect the commander, or turn repeated landfall triggers into lethal pressure.
If you are upgrading from Reap the Tides or a loose Simic good-stuff list, tighten the plan first. Cards such as Scourge of Fleets, Tromokratis, Stumpsquall Hydra, or Pearl Lake Ancient can be fun, but they do not accelerate Aesi or multiply landfall. Three-mana rocks like Commander's Sphere are also weaker here than land-based ramp because lands become cards once Aesi is in play.
Land count, ramp count, and the six-mana problem
Most Aesi lists should begin at 42 lands and 13 ramp pieces. You can move down to 40 lands if your curve is low and you play many cheap extra-land effects. Move up to 43 if you run several utility lands, bounce lands, MDFCs, or seven-mana finishers. Aesi wants lands left in hand after it resolves, so 36-land Simic ramp math is usually too low.
Recommended Aesi ramp package
| Package | Examples | Why it matters | Common cut |
|---|---|---|---|
| Two-mana ramp | Rampant Growth, Nature's Lore, Three Visits, Sakura-Tribe Elder | Gets Aesi down early while fixing green and blue. | Commander's Sphere, Worn Powerstone |
| Land-search spells | Cultivate, Kodama's Reach, Harrow, Roiling Regrowth | Stock your hand or create multiple landfall triggers once Aesi is out. | Expensive draw spells |
| Extra land permanents | Azusa, Dryad, Wayward Swordtooth, Oracle of Mul Daya | Turn Aesi draws into immediate mana and more cards. | One-shot value creatures |
| Budget enablers | Explore, Growth Spiral, Walking Atlas, Sakura-Tribe Scout, Khalni Heart Expedition | Preserve the role of premium cards at a slower pace. | Off-theme sea monsters |

Sample before-and-after upgrade package
| Add | Role | Suggested cut | Reason |
|---|---|---|---|
| Sakura-Tribe Elder | Two-mana land ramp | Commander's Sphere | Gets a land, blocks early, and triggers landfall later. |
| Nature's Lore | Efficient ramp | Worn Powerstone | Finds a Forest dual or basic and keeps ramp land-based. |
| Cultivate | Land access | Stumpsquall Hydra | Guarantees land drops before and after Aesi. |
| Kodama's Reach | Land access | Tromokratis | Improves consistency instead of adding another late threat. |
| Harrow | Burst landfall | Scourge of Fleets | With Aesi out, Harrow creates two draw triggers at instant speed. |
| Khalni Heart Expedition | Budget landfall burst | Pearl Lake Ancient | Cheap early play that cashes in for two lands later. |
| Tireless Provisioner | Treasure or Food engine | Murkfiend Liege | Treasures turn land drops into mana for more ramp, counters, or finishers. |
| Scute Swarm | Token payoff | Sphinx of Uthuun | Creates exponential pressure from ordinary land drops. |
| Beast Within | Universal answer | Low-impact ramp payoff | Aesi needs real interaction, not only more value. |
| Overwhelming Stampede | Budget finisher | Win-more seven-drop | Ends games when tokens are already on board. |
Best landfall upgrades and what they replace
Premium extra land upgrades and budget swaps
Exploration is powerful, but the budget replacements do not work the same way. Choose based on speed, card flow, and how often you keep lands in hand.
Exploration
Premium one-mana extra land effect
Best in high-land builds because it costs only one mana and works immediately. It is weakest when your hand empties before Aesi resolves.
Explore
Budget cantrip ramp
A one-shot effect: you get one extra land play this turn and draw a card. It is safer than tap creatures but not repeatable.
Walking Atlas
Repeatable budget land deployment
Repeatable, but slow. It needs lands in hand, must tap, and dies to artifact removal; run it when you want budget redundancy.
Sakura-Tribe Scout
One-mana creature land enabler
Cheaper than Atlas and excellent early. It also enables Retreat to Coralhelm lines because landfall can untap it.
Landfall payoffs that actually close games
Scute Swarm
Token snowball
Replaces generic big creatures. After six lands, each trigger can copy Scute Swarm, so fetches and Harrow effects become explosive.
Rampaging Baloths
Resilient bodies
Replaces midrange beaters with no landfall text. It makes 4/4 Beasts, which survive small damage sweepers and carry Overrun effects well.
Avenger of Zendikar
One-card army
Replaces expensive sea monsters as the seven-drop of choice. It rebuilds after wipes and every later land grows the team.
Retreat to Coralhelm
Combo-sensitive utility
Replaces low-impact enchantments. Landfall can untap Sakura-Tribe Scout or Walking Atlas; with a bounce land or repeatable land-to-hand effect, that can chain many lands quickly.
Field of the Dead
Land-slot payoff
Replaces a colorless or tapped utility land. It occupies a land slot, rewards varied names, and gives Aesi a token plan without spending a spell slot.
Budget swaps that keep the deck functional
Budget Aesi should preserve roles, not card names. If you cannot buy Azusa, Exploration, Oracle of Mul Daya, or Craterhoof Behemoth, replace their jobs: extra land drops, land access, landfall resources, and a clean combat finish. Do not replace them with random seven-drops that only look good when you are already ahead.
Budget swap table for Aesi upgrades
| Expensive card | Budget replacement | What you lose | When the swap is acceptable |
|---|---|---|---|
| Exploration | Explore or Growth Spiral | Repeatability and one-mana speed | Good for slower pods or first upgrades. |
| Azusa, Lost but Seeking | Walking Atlas or Sakura-Tribe Scout | Immediate multiple land drops | Good if you keep 42+ lands and want repeatable budget redundancy. |
| Oracle of Mul Daya | Courser of Kruphix plus Explore, Growth Spiral, Walking Atlas, or Sakura-Tribe Scout | Top-card land access and an extra land drop in one card | Use two cheaper cards to split Oracle's roles instead of pretending Cultivate is the same effect. |
| Lotus Cobra | Tireless Provisioner | Explosive same-turn mana | Better in grindy games where Treasures stockpile and Food buys time. |
| Avenger of Zendikar | Sporemound or Rampaging Baloths | Immediate massive army | Fine when you need cheaper recurring token production. |
| Craterhoof Behemoth | Overwhelming Stampede, Thunderfoot Baloth, End-Raze Forerunners, Return of the Wildspeaker | The most reliable one-card lethal pump | Best budget route for combat Aesi; Finale of Devastation is powerful but not a budget swap. |
Big mana finisher swaps
These cards occupy the closing package. Choose based on budget, table speed, and whether your group likes deterministic endgames.
Craterhoof Behemoth
Premium combat finisher
Ends games immediately when token makers have built a board, but it is expensive and asks the deck to keep enough creatures on the battlefield.
Overwhelming Stampede
Best budget combat finisher
Usually the cleanest cheap replacement if you have one large creature and a wide token board.
End-Raze Forerunners
Creature-based budget finisher
Costs eight mana but brings a body and gives your team vigilance, trample, and a pump.
Return of the Wildspeaker
Flexible draw or pump
Not a Craterhoof clone, but it can draw a fresh hand or turn a Beast-heavy board into lethal damage.
Finishers: combat tokens versus combo-value wins
Aesi normally wins one of two ways. The fair combat plan uses Scute Swarm, Rampaging Baloths, Avenger of Zendikar, Greensleeves, Maro-Sorcerer, or Field of the Dead to build a board, then ends with Overwhelming Stampede, Thunderfoot Baloth, End-Raze Forerunners, Return of the Wildspeaker, or Craterhoof Behemoth. Field of the Dead is excellent here because it turns normal land sequencing into Zombies while taking a land slot. The combo-value plan uses Retreat to Coralhelm with Sakura-Tribe Scout-style creatures: a land enters, Retreat untaps the Scout, the Scout puts another land in, and bounce lands such as Simic Growth Chamber can return a land to hand to keep the chain moving. This is not automatically infinite in every setup, but it can become very fast and should be disclosed in pregame talks.
Interaction and protection are not optional
Aesi draws attention because it turns every land into another card. If you pass with Aesi and no protection, experienced opponents will usually remove it before you untap. Keep at least eight real answers: cheap counters, flexible removal, and protection that lets your engine survive.
Interaction and protection package
Swan Song
Efficient stack interaction
Trades one mana for many spells that stop Aesi or win the game. The Bird is usually irrelevant.
Counterspell
Baseline permission
Cleanly answers almost anything on the stack and is still reliable in mid-power Commander.
Beast Within
Universal permanent answer
Removes combo pieces, planeswalkers, enchantments, and opposing utility lands.
Pongify
Cheap creature removal
Answers dangerous commanders and combo creatures for one mana.
Heroic Intervention
Board protection
Protects Aesi, token boards, and key engines from many sweepers.
Tamiyo's Safekeeping
Budget single-card protection
A cheap way to protect Aesi or a key payoff from targeted removal.
Mana base upgrades: lands are spells here
Upgrade the mana base in tiers. Budget lists can run basics with Evolving Wilds, Terramorphic Expanse, Myriad Landscape, Bant Panorama, and Simic Growth Chamber. Fetch-style lands are slower on a budget but give two landfall events with Aesi. Bounce lands are risky in land-light hands, yet strong once extra-land effects are online because they reload a land to hand. Midrange lists should add Yavimaya Coast, Dreamroot Cascade, Hinterland Harbor, Rejuvenating Springs if affordable, MDFCs such as Bala Ged Recovery, and utility lands that still cast early green spells. Premium lists add Misty Rainforest-style fetches, Breeding Pool, bond lands, Boseiju, Who Endures, and Otawara, Soaring City.
Mana base cards worth evaluating
Evolving Wilds
Budget landfall enabler
Provides two land entries over two actions when Aesi is out and fixes colors, though it is slower than premium fetch lands.
Terramorphic Expanse
Second budget fetch effect
Redundant with Evolving Wilds and useful when you want more landfall triggers without spending heavily.
Myriad Landscape
Slow ramp land
Enters tapped, but after Aesi resolves it sacrifices into two basics: two landfall triggers, two cards, and extra mana from a land slot.
Boseiju, Who Endures
Premium interaction land
Adds removal to a land slot without costing a spell slot.
Otawara, Soaring City
Premium channel land
Gives the deck a hard-to-counter answer that rarely hurts the mana base.
How to sequence Aesi turns
Do not automatically play every land before casting Aesi. If you already have enough mana, hold one land so Aesi draws immediately. With Aesi in play, Harrow sacrifices one land and finds two untapped basics, creating two draw triggers and often mana to keep playing. Myriad Landscape is slow early, but after Aesi resolves it becomes two cards plus ramp. Holding a fetch land until Aesi is on board is often worth more than cracking it immediately.
- Turns one to three: prioritize green sources, two-mana ramp, and extra land setup over slow payoffs.
- Turns four to five: decide whether you can cast Aesi with a land drop available or whether you need to wait with interaction open.
- First Aesi turn: make at least one land entry immediately, then stop if continuing would expose you to a sweeper without a payoff.
- Closing turn: convert tokens or a huge mana advantage into a finisher rather than drawing cards indefinitely.
Power level and bracket expectations
A budget build with tapped lands, slower land deployment, and combat finishers is usually fair mid-power. A tuned build with Exploration, Azusa, premium fetches, efficient protection, and Retreat to Coralhelm combo lines becomes much faster. In pregame talks, say whether you win through combat tokens, whether you run Scout-plus-Retreat land chains, and how early Aesi usually arrives.
Tune the upgrade path before buying cards
Check the mana base, price the list, then look for budget alternatives by role so your Aesi upgrades improve the deck instead of just increasing the receipt.

FAQ
How many lands should an Aesi Commander deck run?
Most Aesi lists should start at 40 to 43 lands. The commander rewards land entries, so a higher land count improves opening hands, makes extra land effects live, and keeps the draw engine moving after Aesi resolves.
What should I cut from the Aesi precon first?
Start with off-plan expensive creatures such as Tromokratis, Scourge of Fleets, Stumpsquall Hydra, Pearl Lake Ancient, or similar sea monsters in unfocused lists. Also trim three-mana rocks such as Commander's Sphere before cutting land-based ramp.
Is Finale of Devastation a budget Craterhoof Behemoth replacement?
Usually no. Finale is powerful and flexible, but it is often priced like a premium card. Budget combat finishers are more commonly Overwhelming Stampede, Thunderfoot Baloth, End-Raze Forerunners, Return of the Wildspeaker, or similar Overrun effects.
How much interaction does Aesi need?
Run at least eight real interaction pieces, and consider ten if your table is fast. Aesi draws many cards, but the deck still needs ways to protect the commander, answer combo pieces, and stop opposing threats.
Should I hold lands in hand before casting Aesi?
Yes, when you already have enough mana. Holding one land lets Aesi draw immediately after it resolves, which reduces the risk of spending six mana and getting nothing if the commander is removed.
Can Aesi be built without expensive staples?
Yes. Budget versions can use slower extra land effects, basic-heavy mana bases, Tireless Provisioner for Treasure or Food, and combat finishers. The important part is preserving the same functional roles: lands, ramp, extra land deployment, protection, payoffs, and a clear way to end the game.
