Szarel, Genesis Shepherd + Puppeteer Clique + Evereth, Viceroy of Plunder

Szarel, Genesis Shepherd

Puppeteer Clique

Evereth, Viceroy of Plunder

How it works

1. Activate Evereth by sacrificing Puppeteer Clique.
2. When Puppeteer Clique dies, its persist ability and Szarel trigger.
3. Resolve the persist trigger, returning Puppeteer Clique from your graveyard to the battlefield with a -1/-1 counter on it.
4. When Puppeteer Clique enters, it triggers, putting a creature card from an opponent's graveyard onto the battlefield under your control.
5. Resolve the Szarel trigger, putting a number of +1/+1 counters on another creature you control.
6. Resolve the Evereth ability from step 1.
7. Activate Evereth by sacrificing the creature returned in step 4.
8. When the creature dies, Szarel triggers, putting a number of +1/+1 counters on Puppeteer Clique.
9. Resolve the Evereth ability.
10. Repeat.
