Koll, the Forgemaster + Diamond Lion + Concordant Crossroads + Sai of the Shinobi

Koll, the Forgemaster

Diamond Lion

Concordant Crossroads

Sai of the Shinobi

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 elegant loop relies on Concordant Crossroads to grant haste, allowing Diamond Lion to tap the very moment it enters the battlefield. Thanks to Sai of the Shinobi's triggered ability, the Equipment automatically attaches itself upon entry, making Diamond Lion both equipped and ready to sacrifice for three mana while discarding your hand. Because it was equipped when it died, Koll, the Forgemaster steps in to return Diamond Lion directly to your hand, allowing you to recast it and repeat the cycle for infinite colored mana, storm count, and death triggers.
