For the cost, Beechbone is kind of pricey. But the ability to combine him with Ent Draught and then letting him hang around 4-5 damage, while keeping him alive by healing him with Wellinghall Preserver makes Beechbone a ridiculous attacker.
Cannot have restricted attachments. Enters play exhausted.
Response: After Beechbone is declared as an attacker, deal 1 damage to him to deal X damage to the defending enemy. X is the amount of damage on Beechbone.
