Vizier of Remedies + Puppeteer Clique + Phyrexian Altar

Vizier of Remedies

Puppeteer Clique

Phyrexian Altar

How it works

1. Activate Phyrexian Altar by sacrificing Puppeteer Clique.
2. When Puppeteer Clique dies, its persist ability triggers, returning it from your graveyard to the battlefield without a -1/-1 counter on it due to Vizier of Remedies.
3. When Puppeteer Clique enters, it triggers, allowing you to put a creature card from an opponent's graveyard onto the battlefield under your control.
4. Repeat.

This infinite loop transforms an opponent's graveyard into an entire army while fueling your mana reserves. By sacrificing Puppeteer Clique to Phyrexian Altar, you generate any color of mana and send the Clique to the graveyard, which triggers its persist ability. Normally, persist would return it with a -1/-1 counter, but Vizier of Remedies steps in to reduce that counter placement to zero, allowing the Clique to return pristine and trigger its entry ability over and over again to steal every creature from your opponents' graveyards.
