Saw in Half + Burnt Offering + Timeless Witness

Saw in Half

Burnt Offering

Timeless Witness

How it works

1. Cast Saw in Half by paying 2, destroying Timeless Witness 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 Timeless Witness tokens enter the battlefield, they trigger, returning Saw in Half and Burnt Offering from your graveyard to your hand.
3. Cast Burnt Offering by paying and sacrificing a Timeless Witness token, adding plus an additional amount of and/or equal to its mana value minus 2.
4. Repeat.
