Wraith, Vicious Vigilante

A 1/1 body carrying double strike and unconditional evasion is a small chassis wired for one purpose: every point of power you point at it gets counted twice and can't be turned away. The ability named Fear Gas simply makes this creature unblockable, so the opponent's board is irrelevant to whether it connects; no artifact wall, no gang-block, no surprise trade in front of it. That pairing is the whole strategic axis. On its own the card does almost nothing: it dies to any burn spell and trades away most combats it's asked to survive. Its value is entirely conditional on the equipment, auras, and counters that feed it, and on those the double strike doubles the return while the guaranteed connection means the payoff never gets ambushed or chumped. That makes it a Voltron shell in a Detective and Hero costume: a legendary target that converts "make one creature big" into "close the game," so long as the surrounding cards do the feeding. The design tension is the familiar Voltron one, concentrated risk against concentrated reward, but the unblockable-plus-double-strike combination tilts it harder toward the aggressor than most such creatures. The usual defensive answers to a suited-up threat (blocking, ganging up) are precisely the ones this body neutralizes, leaving removal or a race as the cleaner responses and a naked 1/1 as the only thing left to remove if you time it wrong.
