Ratadrabik of Urborg + Saw in Half + Adrix and Nev, Twincasters + Mondrak, Glory Dominus

Ratadrabik of Urborg

Saw in Half

Adrix and Nev, Twincasters

Mondrak, Glory Dominus

How it works

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