Szarel, Genesis Shepherd + Puppeteer Clique + Viscera Seer

Szarel, Genesis Shepherd

Puppeteer Clique

Viscera Seer

How it works

1. Activate Viscera Seer 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 Viscera Seer ability from step 1.
7. Activate Viscera Seer 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 Viscera Seer ability.
10. Repeat.
