Szarel, Genesis Shepherd + Puppeteer Clique + Phantom Train

Szarel, Genesis Shepherd

Puppeteer Clique

Phantom Train

How it works

1. Activate Phantom Train 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 Phantom Train ability from step 1.
7. Activate Phantom Train 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 Phantom Train ability.
10. Repeat.

This clever recycling engine revolves around Phantom Train acting as a reliable sacrifice outlet that constantly feeds your board state. Every time you sacrifice Puppeteer Clique to the Train, its persist ability brings it right back, while Szarel, Genesis Shepherd rewards that sacrifice by pumping up your team with counters. Meanwhile, Puppeteer Clique’s entry trigger continuously raids your opponents' graveyards for fresh fuel to sacrifice, keeping the loop spinning indefinitely.
