Wygand, Lupine Partisan

At the beginning of each upkeep, you
may choose an unequipped creature
you control. If you do, create a Weapon
token and attach it to that creature.
Weapons you control have "Equipped
creature can't be blocked by creatures
with power less than its power."
(Weapons are colorless Equipment artifacts with "Equipped creature has +1/+1" and equip {1}.)
