Urza, Prince of Kroog + Metalworker + Akroma's Memorial

Urza, Prince of Kroog

Metalworker

Akroma's Memorial

How it works

1. Activate Metalworker by tapping it and revealing at least three artifact cards from your hand, adding at least six C.
2. Activate Urza by paying 6, creating a token copy of Metalworker that is a 1/1 Soldier.
3. Repeat using the Metalworker token instead.
4. If you have four or more artifact cards in hand, this combo nets infinite colorless mana, and you may target any artifact you control to get infinite copies of them.

This brilliant assembly turns Metalworker into an absolute mana-producing engine, provided you can keep revealing a handful of artifacts from your hand to fuel its massive tap ability. By spending that surplus of colorless mana on Urza, Prince of Kroog, you can copy your original Metalworker over and over again into fresh, hasty 1/1 Soldier artifact creatures that are immediately ready to tap for even more riches. To ensure your growing robotic army can march straight to victory without interruption, Akroma's Memorial blankets your entire team in a protective wall of keyword abilities—granting flying, first strike, vigilance, trample, haste, and crucial protection from black and red.
