Optimus Prime, Hero // Optimus Prime, Autobot Leader + Mikaeus, the Unhallowed + Sarcatog

Optimus Prime, Hero // Optimus Prime, Autobot Leader

Mikaeus, the Unhallowed

Sarcatog

How it works

1. Activate Sarcatog's second ability by sacrificing Optimus Prime, Hero.
2. When Optimus Prime, Hero dies, its second ability triggers, returning it from your graveyard to the battlefield as Optimus Prime, Autobot Leader.
3. Activate Sarcatog's second ability by sacrificing Optimus Prime, Autobot Leader.
4. When Optimus Prime, Autobot Leader dies, Mikaeus triggers, returning Optimus Prime from your graveyard to the battlefield as Optimus Prime, Hero with a +1/+1 counter on it.
5. Resolve both Sarcatog abilities from steps 1 and 3, giving it +2/+2 until end of turn.
6. Repeat.
