Gnottvold Beastmaster

Trample
Whenever Gnottvold Beastmaster attacks, you
may create a Monster Role token attached to
target non-Human creature you control.
Creatures you control with Monster Roles
attached to them get +1/+1.
{1}{g}: Regenerate Gnottvold Beastmaster. You
may sacrifice a Monster Role token rather
than pay this ability's mana cost.
