Suq'Ata Assassin

Poison as a clock rather than a curiosity, built the only way mid-90s design knew how: stack it on top of an evasion keyword. Fear handles the unblockability, and the attack trigger converts each unblocked connect into a poison counter, so the body is less a beater than a counter dispenser that has to keep getting through. The shape is the whole point. A 1/1 dealing one combat damage is irrelevant; a 1/1 that hands out a poison counter every time it slips past the wall is a ten-turn execution timer, assuming nothing interrupts it. That ten-turn math is the catch, and the reason poison stayed a sideshow for over a decade after this: a single counter per swing is a glacial pace, and the card has no way to widen the spigot on its own. It would take the infect mechanic, which folded poison into damage itself rather than gating it behind a separate trigger, to make poison a real win condition. As an artifact of that earlier philosophy, this is poison as an alternate scoreboard you chip at slowly, a snapshot of how the mechanic worked before Wizards decided slow death by counter needed a faster engine behind it.
