Unstoppable Slasher + The Mycosynth Gardens + Amulet of Vigor + Evereth, Viceroy of Plunder

Unstoppable Slasher

The Mycosynth Gardens

Amulet of Vigor

Evereth, Viceroy of Plunder

How it works

1. Activate The Mycosynth Gardens' third ability by paying 1 and tapping it, causing it to become a copy of Amulet of Vigor.
2. Activate Evereth by sacrificing Unstoppable Slasher.
3. When Unstoppable Slasher dies, its second ability triggers, returning it from your graveyard to the battlefield with two stun counters on it.
4. When Unstoppable Slasher enters, Amulet of Vigor and The Mycosynth Gardens trigger, untapping Unstoppable Slasher twice, which will instead remove both stun counters from Unstoppable Slasher.
5. Resolve the Evereth ability.
6. Repeat from step 2.
