The 2 combo pieces

What must be in place

At least one opponent has lost life this turn.

How to execute it

  1. Activate Yahenni by sacrificing the creature with persist.
  2. The persist ability triggers, returning that creature to the battlefield with a -1/-1 counter on it, as well as a +1/+1 counter due to Gev.
  3. The +1/+1 and -1/-1 counters on that creature are removed as a state-based action.
  4. Resolve the ability from step 1, giving it indestructible until end of turn.
  5. Repeat.
