Havi, the All-Father + Gerrard, Weatherlight Hero + Bloodthrone Vampire

Havi, the All-Father

Gerrard, Weatherlight Hero

Bloodthrone Vampire

How it works

1. Activate Bloodthrone Vampire by sacrificing Gerrard.
2. When Gerrard dies, it and Havi trigger.
3. Resolve the Havi trigger, returning up to one legendary creature card with mana value 3 or less from your graveyard to the battlefield.
4. Holding priority, activate Bloodthrone Vampire by sacrificing Havi.
5. When Havi dies, it triggers, returning Gerrard from your graveyard to the battlefield.
6. Resolve the Gerrard trigger from step 2, failing to exile it as it is no longer in your graveyard and returning Havi from your graveyard to the battlefield.
7. Resolve the Bloodthrone Vampire abilities from step 1 and 4.
8. Repeat.
