Ratadrabik of Urborg | Saw in Half | The Masamune

(and one other card)

Cast
Saw in Half by paying ({2} magic symbol) ({B} magic symbol) , destroying
Adrix and Nev 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.
Put either
Adrix and Nev token into your graveyard due to the legend rule.
Ratadrabik triggers four times from the nontoken and token
Adrix and Nevs dying.
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.
Repeat step 4 for the remaining triggers.
