The 2 combo pieces

What must be in place

If a persist creature is used, it does not have a -1/-1 counter on it.
Otherwise, if an undying creature is used, it does not have a +1/+1 counter on it.
Fallen Ideal attached to a creature you control other than the persist or undying creature.

How to execute it

  1. Activate Fallen Ideal by sacrificing the persist or undying creature.
  2. When the creature dies, its persist or undying ability triggers, returning it from your graveyard to the battlefield without a -1/-1 counter or a +1/+1 counter on it due to Solemnity.
  3. Resolve the Fallen Ideal ability, giving the creature it is attached to +2/+1 until end of turn.
  4. Repeat.
