Time Sieve + Mycosynth Lattice + Bishop of Wings + Arcane Adaptation

Time Sieve

Mycosynth Lattice

Bishop of Wings

Arcane Adaptation

How it works

1. Activate Time Sieve by tapping it and sacrificing five other creatures.
2. When the creatures die as Angels due to Arcane Adaptation, Bishop of Wings' second ability triggers five times.
3. Resolve the first trigger, causing you to create a 1/1 Spirit creature token.
4. When the Spirit enters the battlefield as an Angel due to Arcane Adaptation, Bishop of Wings' first ability triggers, causing you to gain 4 life.
5. Repeat from step 3 for each remaining trigger.
6. Resolve the Time Sieve ability from step 1, causing you to take an extra turn after this one.
7. Repeat each turn.

This intricate setup turns your entire board into an endless engine of recurring time by rewriting the very nature of your permanents. With Mycosynth Lattice turning everything into artifacts and Arcane Adaptation declaring all your creatures to be Angels, Bishop of Wings suddenly finds itself surrounded by feathered friends every time anything dies or enters the battlefield. You sacrifice those creatures to Time Sieve to take an extra turn, triggering the Bishop to flood your board with Spirit tokens that immediately count as Angels, which in turn fuels a steady stream of life and fresh fodder to repeat the loop indefinitely.
