Koll, the Forgemaster + Diamond Lion + Sai of the Shinobi + Dynaheir, Invoker Adept

Koll, the Forgemaster

Diamond Lion

Sai of the Shinobi

Dynaheir, Invoker Adept

How it works

1. Cast Diamond Lion by paying 2.
2. When Diamond Lion enters, Sai of the Shinobi 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 clever loop is orchestrated by Koll, the Forgemaster, whose passive ability ensures that whenever an equipped nontoken creature dies, it bounces straight back to your hand instead of hitting the graveyard. Diamond Lion serves as our self-sacrificing engine, burning through your hand to generate three mana, which neatly pays for its own recast while feeding the combo. To bridge the gap, Sai of the Shinobi automatically equips itself to the Lion the moment it enters the battlefield, satisfying Koll's crucial "equipped" requirement so the bounce trigger always resolves. Meanwhile, Dynaheir, Invoker Adept stands ready on the board, granting haste to all your other creatures' abilities—though her presence here is largely a supportive teammate while the Lion, Koll, and Sai endlessly recur to generate infinite mana, storm count, and death triggers.
