Ol' Bizbark of Highland Wood

Saproling creatures you control must attack
each turn if able.
At the beginning of combat on your turn, put
a 1/1 green Saproling creature token onto the
battlefield. It gains haste until end of turn.
Whenever a Saproling you control deals combat
damage to a player, put a +1/+1 counter on it.
GET OFF MY LAWN! It fights back!
