The Master, Formed Anew
Yahenni, Undying Partisan

   Prerequisites

What do I need to start this combo?
The Master and Yahenni on the battlefield.
Persist Creature and Undying Creature in exile (Persist Creature and Undying Creature with a takeover counter on it in exile).
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.

   Steps

How does this combo work?
1
Activate Yahenni by sacrificing The Master.
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
Resolve the Yahenni ability.
5
Repeat.
