Devastating Onslaught + Mana Geyser + Returned Pastcaller

Devastating Onslaught

Mana Geyser

Returned Pastcaller

How it works

1. Cast Mana Geyser by paying 3, adding for each tapped land your opponents control.
2. Cast Devastating Onslaught by paying 4, creating two token copies of Returned Pastcaller with haste.
3. When the Returned Pastcaller tokens enter, they trigger, returning Mana Geyser and Devastating Onslaught from your graveyard to your hand.
4. Repeat.

This explosive loop turns your opponents' heavily tapped board into an engine of continuous recursion. By casting Mana Geyser, you harvest a massive surge of red mana fueled by your opponents' tapped lands, which then funds Devastating Onslaught. The Onslaught creates a pair of hasty token copies of Returned Pastcaller, and when those flying Spirits enter the battlefield, their triggered abilities reach into your graveyard to pull both Mana Geyser and Devastating Onslaught right back to your hand.
