Cascade, segmented (When this creature dies, if its
base toughness is 2 or greater, create a token that's a
copy of it except it has base power and toughness
X/X, where X is half this creature's base toughness,

Merfolk, Fish, Kraken, and other Leviathan
creatures you control have cascade.

followers."
