Crawling Chorus

Toxic changed the rules of engagement for combat damage: a hit no longer has to be lethal to matter, it just has to connect. This one-drop is one of the cleanest expressions of that idea, because it is engineered to keep delivering poison even after it dies. A single counter per swing looks trivial, but the death trigger hands you a Phyrexian Mite that carries its own toxic, so killing the body doesn't stop the poison clock: it relocates it to a token that can't block anyway. That trigger is what turns a fragile 1/1 into a two-for-one on the poison axis. The Mite's inability to block is the honest tax on that value: you get a persistent attacker, not a wall, which keeps the card pointed forward in exactly the direction poison strategies want to go. Structurally it does the work older sacrifice-fodder aristocrat one-drops did on the death-trigger axis, except the payoff is measured in counters toward the ten a corrupted player needs rather than raw damage or drain. The math is patient by design: even ignored, the creature and its Mite chip at a total that never resets, which is the whole distinction between poison and ordinary combat damage. This is a builder's block, meant to be stacked with other toxic sources until the incremental counters accumulate faster than an opponent can race them.
