Chronozoa + Solemnity + Phantom Train

Chronozoa

Solemnity

Phantom Train

How it works

1. Cast Chronozoa by paying 3. It will enter without a time counter on it due to Solemnity.
2. Activate Phantom Train by sacrificing Chronozoa.
3. When Chronozoa dies, it triggers, creating two token copies of itself that also enter with no time counters on them due to Solemnity.
4. Resolve the Phantom Train ability.
5. Repeat from step 2 using a token copy of Chronozoa instead.

This loop relies on the brilliant interaction between Chronozoa and Solemnity, where Solemnity’s passive ability prevents time counters from ever being placed, ensuring that Chronozoa immediately meets its dying condition with zero counters whenever it hits the graveyard. By feeding one of these copies to Phantom Train's activated ability, you trigger Chronozoa's death clause to birth two fresh token copies—both of which also bypass vanishing entirely thanks to Solemnity. Meanwhile, Phantom Train grows steadily stronger with a +1/+1 counter from each sacrifice, ultimately generating an unbounded loop of leaves-the-battlefield, entry, and death triggers to overwhelm your opponents.
