Polymer Pits Commando Ape

When Polymer Pits Commando Ape enters,
you may put a forestwalk or vigilance counter
on it. If you don't, it gains haste and "Polymer Pits Commando Ape attacks each combat if
able and must be blocked if able."
Whenever Polymer Pits Commando Ape
attacks, other attacking creatures you control
that share a creature type with it get +1/+0
and gain menace until end of turn.
