Urza, Prince of Kroog + Grim Monolith + Anointed Procession + Akroma's Memorial

Urza, Prince of Kroog

Grim Monolith

Anointed Procession

Akroma's Memorial

How it works

1. Activate Grim Monolith's first ability by tapping it, adding CCC.
2. Activate Urza by paying 6, creating two token copies of Grim Monolith that are 1/1 Soldiers in addition to their other types.
3. Activate both Grim Monolith tokens' first abilities by tapping them, adding six C.
4. Repeat from step 2.

This explosive engine transforms raw mana into a massive, unstoppable army by exploiting a duplication loop. With Grim Monolith providing the initial energy, Urza, Prince of Kroog uses its massive activation cost to copy that very artifact; thanks to Anointed Procession doubling that yield into two artifact creature tokens every single time, the math quickly spirals out of control and generates infinite mana. Once your digital workshop is spinning out of control, Akroma's Memorial steps in to coat the entire resulting horde in a glorious suite of keywords—giving your newly minted Soldier tokens flying, haste, trample, and more so they can immediately crush the opposition.
