Urza, Prince of Kroog + Doubling Cube + Thousand-Year Elixir

Urza, Prince of Kroog

Doubling Cube

Thousand-Year Elixir

How it works

1. Float at least 10.
2. Activate Doubling Cube by paying 3 and tapping it, adding at least 7.
3. Activate Urza by paying 6, creating a token copy of Doubling Cube that is a 1/1 Soldier.
4. Repeat from step 2 using the Doubling Cube token instead.
5. Once you have infinite mana, you may target any artifact you control to get infinite copies of them.

By harnessing the exponential growth of Doubling Cube, this setup turns a massive mana pool into an unstoppable engine of replication. Thousand-Year Elixir provides the crucial haste-like speed for creature abilities, letting you continually untap Urza, Prince of Kroog so his steep activation cost can be paid over and over again. As Urza floods the board with token copies of Doubling Cube, each new iteration doubles your mana output even further until you achieve infinite mana. From there, Urza's ability can be redirected to any artifact you control, leaving your opponents utterly overwhelmed by an infinite army of your favorite toys.
