[Blocker] Blocker
Evolution: Put on 1 of your creatures with "Blocker"
Double Breaker
Any effect that would prevent your creatures with "Blocker" from attacking is negated. (This includes summoning sickness, this creature can't attack, and this creature can't attack players.)
At the end of your turn, untap all of your creatures in the battle zone that have "White Knight" in their name.
