Aesi, Tyrant of Gyre Strait - Intelligence

Aesi turns every land into momentum: it gives you another land play each turn and converts every land entering under your control into an optional card draw.

Use a turn-level allowance: count lands already played this turn, calculate current permitted land plays from Aesi, Exploration, Azusa, Oracle of Mul Daya, and similar effects, then allow another land play only when used count is below current allowance.

Resolving Aesi after the normal land play can permit another land play if the current allowance exceeds lands already played.

Using Aesi's extra land permission before Aesi leaves does not create a reusable object-specific land-play charge.

Blinking Aesi does not automatically grant a fresh land play; only the current turn-level allowance matters.

Multiple legal nonlegendary Aesi copies add multiple additional-land permissions and create multiple draw triggers from the same land entry.

Playing a land consumes a land play and follows timing; putting a land onto the battlefield through fetches, ramp, Scouts, Walking Atlas, Splendid Reclamation, or Scapeshift does not consume a land play but still causes Aesi to trigger.

Each Aesi trigger resolves independently and its controller may draw one card. Declining is legal and can matter for deck-out, draw punishment, top-card preservation, or combo sequencing.

Multiple lands entering simultaneously create one Aesi trigger per land, not one aggregate trigger.

A fetch land normally creates one trigger when the fetch enters and another trigger when the searched land enters under Aesi's controller's control.

Land tokens and land creatures such as Dryad Arbor trigger Aesi as lands; creating a land token does not consume a land play.

A modal double-faced card played as a land consumes a land play and triggers Aesi; casting its spell face does not.

Transforming an existing permanent into a land does not create a land-entry event.

Returning a land to hand does not trigger Aesi; replaying it later does and consumes a land play.

Abundance can replace Aesi's draw. When replaced, the selected card is not drawn for draw-trigger purposes.

When Mystic Sanctuary and Aesi triggers are controlled by the same player, that player can stack Aesi first and Sanctuary above it, put an instant or sorcery on top, then draw it with Aesi.

Playing a land from a graveyard consumes a land play; returning a land directly to the battlefield does not.

If Aesi leaves before a land enters, no Aesi trigger is created. If the land already entered and triggered Aesi, removing Aesi does not remove that trigger.

Glacial Chasm plus Ramunap Excavator is a repeatable damage-prevention engine, not an infinite win or universal lock.

Resolve Aesi with a land entry ready, then chain fetches, land ramp, and graveyard land plays into optional draws.

Convert every land entry into bodies or resources while Aesi keeps the cards flowing.

Use Ramunap Excavator, Crucible effects, Life from the Loam, and mass recursion to replay or return lands repeatedly.

Use Aesi's optional draw and extra land play as the rules glue for Sanctuary, Tidal Bore, Abundance, or Walking Atlas loops.
