Jinnie Fay, Jetmir's Second + Gemcutter Buccaneer + Xenograft

Jinnie Fay, Jetmir's Second

Gemcutter Buccaneer

Xenograft

How it works

1. Cast Gemcutter Buccaneer by paying 3.
2. When Gemcutter Buccaneer enters the battlefield, it triggers, creating a tapped 2/2 Cat or 3/1 Dog creature token due to Jinnie Fay.
3. When the Cat or Dog enters the battlefield as a Pirate due to Xenograft, Gemcutter Buccaneer triggers, creating a tapped 2/2 Cat or 3/1 Dog creature token due to Jinnie Fay.
4. Repeat step 3.

This clever loop transforms every newly minted animal into a fresh trigger for an infinite army. With Xenograft naming "Pirate," every creature you control joins the crew, allowing Jinnie Fay, Jetmir's Second to turn the tapped Treasure tokens normally generated by Gemcutter Buccaneer into fresh Cats or Dogs instead. Because these tokens enter as Pirates thanks to Xenograft, Gemcutter Buccaneer sees them arrive and triggers all over again, creating a self-sustaining loop of endless creature tokens.
