Mistford River Turtle

A 1/5 body is not built to hit; it is built to survive combat while it does its real job, which is opening a hole for something else. The evasion granted here is conditional in a way most unblockable-enablers are not: the beneficiary has to be another attacking non-Human creature, so the card only pays out inside a wide, tribal-flavored attack where you already have bodies coming across. That restriction is the design's whole shape. Rather than making one big threat unblockable at instant speed, it rewards committing a crew to the red zone and then choosing which of them slips through, turn after turn, since the body is durable enough to keep attacking without dying. The Human exclusion is the flavor tell and the balancing lever at once: it steers the ability toward the non-Human folk-tale creatures it was designed to enable and quietly keeps it from turning a stock Human-heavy board into an unblockable machine. What you get is a repeatable, defensively-statted evasion granter, an aggressive tool that asks you to build around a creature type rather than around a single finisher.
