{T}: Remove target blocking creature from combat. Creatures it was blocking that hadn't become blocked by another creature this combat become unblocked, then it blocks an attacking creature of your choice. Activate only during the declare blockers step.

Flanking (Whenever a creature without flanking blocks this creature, the blocking creature gets -1/-1 until end of turn.) Other creatures you control with flanking have flanking. (Each instance of flanking triggers separately.)
