Long Feng, Grand Secretariat + Bloodthrone Vampire

Long Feng, Grand Secretariat

Bloodthrone Vampire

How it works

1. Activate Bloodthrone Vampire by sacrificing a persist creature that doesn't have a -1/-1 counter on it.
2. When the creature dies, its persist ability and Long Feng trigger.
3. Resolve the Long Feng trigger, putting a +1/+1 counter on the other persist creature.
4. Resolve the persist trigger, returning the creature from your graveyard to the battlefield with a -1/-1 counter on it.
5. Resolve the Bloodthrone Vampire ability.
6. Repeat.
