Thran Vigil + Yahenni, Undying Partisan + Obstinate Gargoyle

Thran Vigil

Yahenni, Undying Partisan

Obstinate Gargoyle

How it works

1. Activate Yahenni by sacrificing Obstinate Gargoyle.
2. When Obstinate Gargoyle dies, its persist ability triggers, returning it from your graveyard to the battlefield with a -1/-1 counter on it.
3. Thran Vigil triggers, putting a +1/+1 counter on Obstinate Gargoyle.
4. Resolve the Yahenni ability.
5. Repeat.
