Blasting Station + Puppeteer Clique + Hardened Academic

Blasting Station

Puppeteer Clique

Hardened Academic

How it works

1. Activate Blasting Station by tapping it and sacrificing Puppeteer Clique.
2. When Puppeteer Clique dies, its persist ability triggers, returning it from your graveyard to the battlefield with a -1/-1 counter on it.
3. Hardened Academic, Blasting Station and Puppeteer Clique trigger.
4. Resolve the Blasting Station trigger, untapping it.
5. Resolve the Hardened Academic trigger, putting a +1/+1 counter on Puppeteer Clique.
6. Resolve the Puppeteer Clique trigger, allowing you to put a creature card from an opponent's graveyard onto the battlefield under your control.
7. Resolve the Blasting Station ability from step 1
8. Repeat.

This ingenious loop turns a gruesome recursive cycle into absolute devastation, letting you pillage your opponents' graveyards while blasting them to ashes. By feeding Puppeteer Clique to Blasting Station, you trigger the Clique's persist ability to bring it right back alongside a helpful untap from the Station. Normally, the -1/-1 counter from persist would shut down future returns, but Hardened Academic steps in to place a +1/+1 counter on the Clique whenever cards leave your graveyard, gracefully neutralizing the -1/-1 counter through counter annihilation. This allows you to infinitely sacrifice the Clique to deal damage, constantly triggering its enter-the-battlefield ability to steal every creature your opponents have ever laid to rest.
