Saw in Half

Ardent Elementalist

How it works

1. Cast Culling the Weak by paying and sacrificing another creature, adding .
2. Cast Saw in Half by paying 2, destroying Ardent Elementalist 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.
3. When the Ardent Elementalist tokens enter the battlefield, they trigger, returning Saw in Half and Culling the Weak from your graveyard to your hand.
4. Repeat.
