Jinnie Fay, Jetmir's Second + Samwise Gamgee + Cloudstone Curio + Kobolds of Kher Keep

Jinnie Fay, Jetmir's Second

Samwise Gamgee

Cloudstone Curio

Kobolds of Kher Keep

How it works

1. Cast Kobolds of Kher Keep by paying 0.
2. When Kobolds of Kher Keep enters the battlefield, Samwise Gamgee's first ability and Cloudstone Curio trigger.
3. Resolve the Cloudstone Curio trigger, returning nothing to your hand.
4. Resolve the Samwise Gamgee trigger, creating a 2/2 Cat creature token with haste due to Jinnie Fay.
5. When the Cat enters the battlefield, Cloudstone Curio triggers, returning Kobolds of Kher Keep from the battlefield to your hand.
6. Repeat.

This clever loop harnesses free zero-mana creatures to churn out an endless army of hasty attackers. When you cast Kobolds of Kher Keep for nothing, Samwise Gamgee triggers to generate a token, which Jinnie Fay, Jetmir's Second brilliantly converts into a 2/2 Cat with haste instead of a standard Food or Treasure. That entering Cat triggers Cloudstone Curio, allowing you to bounce the original Kobolds of Kher Keep right back to your hand so you can recast it all over again.
