Invasion of Amonkhet // Lazotep Convert + Ojer Kaslem, Deepest Growth // Temple of Cultivation + Phantom Train

Invasion of Amonkhet // Lazotep Convert

Ojer Kaslem, Deepest Growth // Temple of Cultivation

Phantom Train

How it works

1. Defeat Invasion of Amonkhet
2. Invasion of Amonkhet triggers, causing you to exile it, and return it to the battlefield transformed as Lazotep Convert.
3. Choose to have Lazotep Convert enter the battlefield as a copy of Ojer Kaslem that is a 4/4 Zombie.
4. Activate Phantom Train by sacrificing Lazotep Convert.
5. When Lazotep Convert dies, it triggers, causing you to exile it, and return it to the battlefield transformed as Lazotep Convert.
6. Choose to have Lazotep Convert enter the battlefield as a copy of Ojer Kaslem that is a 4/4 Zombie.
7. Resolve the Phantom Train ability
8. Repeat from step 4.

This loop relies on an ingenious cloning interaction made possible by Invasion of Amonkhet // Lazotep Convert, which transforms into Lazotep Convert and lets it enter the battlefield as a copy of Ojer Kaslem, Deepest Growth // Temple of Cultivation while retaining its own copy-related triggers when it dies. By using Phantom Train to repeatedly sacrifice this copy, you trigger its death-and-return cycle indefinitely, creating an endless loop of creature enters-the-battlefield, leaves-the-battlefield, and sacrifice events. At the same time, sacrificing the creature fuels Phantom Train's activated ability to keep growing its own +1/+1 counters without end.
