Jinnie Fay, Jetmir's Second + Thorin, King of Durin's Folk + Conspiracy

Jinnie Fay, Jetmir's Second

Thorin, King of Durin's Folk

Conspiracy

How it works

1. Cast Thorin by paying 3.
2. When Thorin enters, it triggers, creating a 2/2 Cat creature token with haste due to Jinnie Fay.
3. When the Cat enters as a Dwarf due to Conspiracy, Thorin triggers, creating a 2/2 Cat creature token with haste due to Jinnie Fay.
4. Repeat step 3.

This engine transforms a single Dwarf entry into a torrential wave of creatures, fueled entirely by the clever synergy among your permanents. With Conspiracy naming "Dwarf" as it enters, every creature you control instantly becomes a Dwarf, meaning the token generated by Jinnie Fay, Jetmir's Second will itself be a Dwarf. That newly spawned token instantly triggers Thorin, King of Durin's Folk to create a Treasure token, which Jinnie Fay's replacement effect redirects into another hasty 2/2 Cat token instead. Because that fresh token arrives as a Dwarf, it loops right back into Thorin's trigger, creating an infinite cascade of entering creatures and hasty tokens.
