Urza, Prince of Kroog + Grim Monolith + Anointed Procession + Lightning Greaves

Urza, Prince of Kroog

Grim Monolith

Anointed Procession

Lightning Greaves

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 Lightning Greaves' equip ability by paying 0, attaching it to a Grim Monolith token.
4. Activate the Grim Monolith token's first ability by tapping it, adding CCC.
5. Repeat from step 3 using the other Grim Monolith token.
6. Repeat from step 2.

This ingenious loop lets you scale your mana production exponentially by leveraging the artifact-copying prowess of Urza, Prince of Kroog alongside the token-doubling might of Anointed Procession. When Urza's sixth ability targets a tapped Grim Monolith, Anointed Procession steps in to double your yield, instantly flooding the board with duplicate mana rocks that enter untapped and ready to tap for three colorless mana each. By shuffling Lightning Greaves around for free, you shield your newly minted artifact creatures while tapping them in succession to continuously fund the next activation of Urza, Prince of Kroog. Ultimately, Urza's passive anthem pumps these freshly generated tokens to 3/3 soldiers while you build an infinite army of artifact creatures that can immediately swarm the opponent.
