Coercive Recruiter + Marrow-Gnawer + Maskwood Nexus

Coercive Recruiter

Marrow-Gnawer

Maskwood Nexus

How it works

1. Activate Marrow-Gnawer by tapping it and sacrificing another creature, creating at least two 1/1 Rat creature tokens.
2. When the Rats enters the battlefield as a Pirate due to Maskwood Nexus, Coercive Recruiter triggers twice, untapping Marrow-Gnawer, and causing you to untap any other creature and gain control of it until end of turn.
3. Repeat.

This loop relies on Maskwood Nexus to turn your entire battlefield into a unified family, ensuring that every creature you control is simultaneously a Rat, a Pirate, and every other creature type in the game. With that type-matching foundation laid, you tap Marrow-Gnawer to sacrifice one of those creatures and flood the board with new Rat tokens. Because of the Nexus, those incoming tokens immediately trigger Coercive Recruiter's ability twice, which untaps Marrow-Gnawer and lets you steal and untap other creatures. By looping this sacrifice and reentry, you generate infinite creature tokens, endless enters-the-battlefield triggers, and total control of the opponent's board.
