Wabu Shield-Wall

Defender Shield-Wall — Wabu Shield-Wall can block an additional number of creatures each combat equal to the number of shield counters on it. Other creatures you control get +1/+1 for each shield counter on Wabu Shield-Wall. Party Up — Whenever another creature enters the battlefield under your control, put a shield counter on Wabu Shield-Wall. Break the Line — As long as Wabu Shield-Wall has ten or more shield counters on it, it can attack as though it didn’t have defender and assigns combat damage equal to its toughness instead of its power. When it does, remove ten shield counters from it. When Wabu Shield-Wall dies, return it to the battlefield transformed under your control. Transforms into → Wabu’s Adamantine Shield
