Havi, the All-Father + Gerrard, Weatherlight Hero + Hammerhead, Maggia Boss

Havi, the All-Father

Gerrard, Weatherlight Hero

Hammerhead, Maggia Boss

How it works

1. Activate Hammerhead 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 Hammerhead 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 Hammerhead abilities from step 1 and 4.
8. Repeat.
