Wall of Caltrops

Defender (This creature can't attack.) Whenever this creature blocks a creature, if at least one other Wall creature is blocking that creature and no non-Wall creatures are blocking that creature, this creature gains banding until end of turn. (If any creatures with banding you control are blocking a creature, you

divide that creature's combat damage, not its controller, among any of the creatures it's being blocked by.)
