Time Sieve + Mycosynth Lattice + Bishop of Wings + Conspiracy

Time Sieve

Mycosynth Lattice

Bishop of Wings

Conspiracy

How it works

1. Activate Time Sieve by tapping it and sacrificing five other creatures.
2. When the creatures die as Angels due to Conspiracy, 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 Conspiracy, 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 fascinating interaction turns the entire board into a relentless engine for infinite turns, enabled by the subtle power of Mycosynth Lattice and Conspiracy. With Mycosynth Lattice making every permanent on the battlefield an artifact, and Conspiracy redefining all your creatures as Angels, your creatures effortlessly satisfy Time Sieve's sacrifice requirement while simultaneously triggering Bishop of Wings. As those sacrificed creatures hit the graveyard, Bishop of Wings replaces their loss by spawning Spirits that immediately enter as Angels due to Conspiracy, generating the necessary fodder and a massive cushion of life to sustain your looping extra turns.
