Koll, the Forgemaster + Diamond Lion + Dragonlord Kolaghan + Ronin Warclub

Koll, the Forgemaster

Diamond Lion

Dragonlord Kolaghan

Ronin Warclub

How it works

1. Cast Diamond Lion by paying 2.
2. When Diamond Lion enters, Ronin Warclub triggers, attaching itself to Diamond Lion.
3. Activate Diamond Lion by tapping it, sacrificing it and discarding your hand, adding three mana of any color.
4. When Diamond Lion dies, Koll triggers, returning Diamond Lion from your graveyard to your hand.
5. Repeat.

This loop relies on an ingenious self-equipping mechanism where Diamond Lion becomes instantly ready to sacrifice the moment it hits the battlefield, thanks to Ronin Warclub automatically strapping on to boost it into an equipped creature. Because that equipment makes it eligible, Koll, the Forgemaster catches the dying cat when you cash it in for mana, bouncing it straight back to your hand so you can recast it endlessly. Dragonlord Kolaghan sits proudly in the command zone or your 99 as a legal consideration for color identity and deckbuilding, rounding out the shell while your artifacts and legends execute the infinite loop.
