Aya of Alexandria + Breath of Fury + Mycosynth Lattice + Frostcliff Siege

Aya of Alexandria

Breath of Fury

Mycosynth Lattice

Frostcliff Siege

How it works

1. Deal combat damage using the creature that has Breath of Fury attached.
2. Breath of Fury and Aya of Alexandria trigger.
3. Resolve the Aya of Alexandria trigger, creating a 1/1 Assassin creature token.
4. Resolve the Breath of Fury trigger, causing you to sacrifice the creature it is attached to, then attach Breath of Fury to the Assassin token, then causing you to untap all creatures you control and to get an additional combat phase after this one.
5. Repeat each combat phase.

This ingenious loop turns every historic creature into an engine for infinite combat steps, quietly orchestrated by Mycosynth Lattice to ensure everything on your board—including Aya of Alexandria and the tokens she spawns—counts as an artifact and therefore a historic permanent. Once you enchant a creature with Breath of Fury and swing, the resulting combat damage triggers both Aya of Alexandria to make a new Assassin token and Breath of Fury to sacrifice your attacker, move the Aura to the fresh token, untap your entire board, and grant you an additional combat phase. Meanwhile, Frostcliff Siege pumps up your team with trample and haste and rewards every single combat phase with a fresh card draw.
