Water Tuskfin

Combine Mass (Whenever you cast a spell that
raises this creatures power or toughness until end of
turn, you may instead choose to create a number of
"Mass" tokens that have "Sacrifice this token:
Give target creature +X/+Y until end of turn"
equal to the amount of power and toughness gained,
where X and Y are equal to the power and toughness respectively.)
Good memory, big tusks.
