Urza, Prince of Kroog + Doubling Cube + Akroma's Memorial
How it works
- Float at least 10.
- Activate Doubling Cube by paying 3 and tapping it, adding at least 7.
- Activate Urza by paying 6, creating a token copy of Doubling Cube that is a 1/1 Soldier.
- Repeat from step 2 using the Doubling Cube token instead.
- Once you have infinite mana, you may target any artifact you control to get infinite copies of them.
This explosive mana-multiplication engine turns a surplus of resources into boundless wealth and a lethal army. By sinking floating mana into Doubling Cube's ability to multiply your pool, you generate enough energy to fund Urza, Prince of Kroog's six-mana activation, which weaves a fresh, functioning copy of the Cube into a 1/1 Soldier artifact creature. From there, the new token can immediately repeat the process at an escalating profit, and once your mana is infinite, Urza pivots to mass-duplicating any other artifact you control. To ensure that this sprawling mechanical menagerie can instantly overwhelm your opponents, Akroma's Memorial blankets your entire team—including every newly forged artifact creature copy—in a devastating array of keywords like flying, trample, and haste.
