Ratadrabik of Urborg + Saw in Half + Mondrak, Glory Dominus + Elspeth, Storm Slayer

Ratadrabik of Urborg

Saw in Half

Mondrak, Glory Dominus

Elspeth, Storm Slayer

How it works

1. Cast Saw in Half by paying 2, destroying Mondrak and creating four 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. Put all but one Mondrak token into your graveyard due to the legend rule.
3. Ratadrabik triggers four times from the nontoken and token Mondraks dying.
4. Resolve the first trigger, creating 2^X nonlegendary token copies of Mondrak that are 2/2 Zombies, where X is the number of Mondraks you control plus one.
5. Repeat step 4 for the remaining triggers.
