Undercity Uprising

Most fight spells ask you to find a creature big enough to win the exchange, and that hunt for a favorable matchup is the whole tax on the effect. This one settles the tax up front: the blanket deathtouch resolves before the fight, so the creature you choose to throw the punch needs only a single point of power to kill whatever it touches. The fight clause, normally the half of a Prey Upon-style effect that rewards a big body, here launders a removal spell through your smallest attacker while your real threats stay parked and unspent. The line that makes it sing is mass deathtouch into a fight from a token or a one-drop: poison teeth spread across your whole board, and any creature you own can answer nearly anything the opponent fields. Paying for that flexibility means eating the sorcery timing and the dual-target requirement (you need one of your own creatures and one of theirs already in play), so it can never operate as a clean instant-speed trick. Read it as a removal spell dressed up in combat-trick clothing, with the deathtouch grant doing the work that targeted destruction does in mono-black, only handed out to every creature you control until the turn ends.
