Phase Dolphin

Evasion granted by an attacker, not carried on one: the design here is that this creature never needs to connect itself. Its 1/4 body is built to swing in every turn (four toughness means it survives most of what an early defender throws at it) precisely so it can keep pointing the unblockable clause at the creature that actually matters. That splits the usual evasion package in two. Where a flyer or a menace creature carries its own path through, this one is a repeatable delivery mechanism: attach the effect to the fattest threat on your board, or to whatever creature is wearing the Auras, and let the durable body eat the chump block that would otherwise stall the alpha strike. What holds it back from oppression is a pair of limits: the ability only fires on its own attack and only frees one other creature, so it wants a board wide enough to have a real second threat and a life total healthy enough to send a defensive-shaped body into the red zone every turn. It is a support piece for a beatdown plan built around a single evasion payoff, doing the enabling work while a scarier creature does the killing.
