The 2 combo pieces

What must be in place

The Master on the battlefield as a copy of either the persist or undying creature.
The Master does not have a +1/+1 counter on it if it is a copy of the undying creature, or a -1/-1 counter on it otherwise.

How to execute it

  1. Activate Thermopod's second ability by sacrificing The Master, adding {R}.
  2. When The Master dies, if it was a copy of the undying creature, its undying ability triggers, returning it from your graveyard to the battlefield as a copy of the persist creature with a +1/+1 counter on it.
  3. Otherwise, if The Master was a copy of the persist creature, its persist ability triggers, returning it from your graveyard to the battlefield as a copy of the undying creature with a -1/-1 counter on it.
  4. Repeat.
