Mischievous Quanar + Mana Geyser + Mycosynth Lattice

Mischievous Quanar

Mana Geyser

Mycosynth Lattice

How it works

1. Cast Mana Geyser by paying 5.
2. Holding priority, activate Mishchievous Quanar's morph ability by paying 3, turning it face up.
3. Mischievous Quanar triggers, copying Mana Geyser.
4. Resolve the copy of Mana Geyser, adding 1 for each tapped land your opponents control.
5. Activate Mischievous Quanar's first ability by paying 5, turning it face down.
6. Repeat from step 2.
7. If opponents control nine or more tapped lands, this combo nets infinite mana, which you can then use to activate Mischievous Quanar to get infinite copies of any other instant and/or sorcery spell(s) on the stack.

This ingenious loop relies on turning your opponents' lands against them to fuel an endless cycle of morph and unmorph actions. With Mycosynth Lattice unifying the battlefield, your spells and permanents become colorless, but more importantly, it sets the stage for a massive Mana Geyser that nets a huge influx of red mana based on your opponents' tapped lands. You then use Mischievous Quanar to copy that initial Mana Geyser, before turning it face down and back up again to repeat the process. As long as your opponents control nine or more tapped lands, the copied mana more than pays to reset Mischievous Quanar each time, netting infinite mana and infinite spell copies.
