Time Sieve + Encroaching Mycosynth + Rotlung Reanimator + Xenograft

Time Sieve

Encroaching Mycosynth

Rotlung Reanimator

Xenograft

How it works

1. Activate Time Sieve by tapping it and sacrificing five other creatures.
2. When the creatures die as Clerics due to Xenograft, Rotlung Reanimator triggers five times, creating five 2/2 Zombie creature tokens.
3. Resolve the Time Sieve ability, causing you to take an extra turn after this one.
4. Repeat each turn.
