Coercive Recruiter + Bloodline Keeper // Lord of Lineage + Xenograft

Coercive Recruiter

Bloodline Keeper // Lord of Lineage

Xenograft

How it works

1. Activate Bloodline Keeper by tapping it, creating a 2/2 Vampire creature token.
2. When the Vampire enters the battlefield as a Pirate due to Xenograft, Coercive Recruiter triggers, untapping Coercive Recruiter.
3. Repeat.

This elegant loop turns an ordinary token-maker into a perpetual motion machine by completely rewriting creature types. With Xenograft on the board naming "Pirate," every new arrival from Bloodline Keeper enters as both a Vampire and a Pirate. That sneaky type-shifting is all Coercive Recruiter needs to see, triggering its ability upon each token's entry to untap itself—or in this case, fueling the loop by continually welcoming new recruits. Because Bloodline Keeper can be tapped repeatedly to spawn these hybrid tokens, you generate an unbounded number of creatures and enter-the-battlefield triggers.
