Saw in Half + Sacrifice + Revolutionist

Saw in Half

Sacrifice

Revolutionist

How it works

1. Cast Saw in Half by paying 2, destroying Revolutionist and creating two token copies of it with base power equal to half the destroyed creature's power and base toughness equal to half the destroyed creature's toughness, rounding up each time.
2. When the Revolutionist tokens enter the battlefield, they trigger, returning Saw in Half and Sacrifice from your graveyard to your hand.
3. Cast Sacrifice by paying and sacrificing a Revolutionist token, adding an amount of equal to its mana value.
4. Repeat.

This loop is an engine of recursive recycling, fueled by Saw in Half to continually multiply your resources. By targeting Revolutionist with that spell, you trigger its entry ability twice to pull both Saw in Half and Sacrifice right back out of your graveyard and into your hand. You then feed one of the resulting token copies to Sacrifice to fund the next iteration, generating a surplus of black mana while keeping the loop completely self-sustaining.
