Bloodletter

Most black creatures with a board-wiping death rattle demand something concrete: a sacrifice outlet, a life payment, a counter cleared off first. This 2/3 instead sacrifices itself when it notices a coincidence, three or more nonland permanents on the battlefield whose names begin with the same letter, and pays out with a two-point sweep to every creature and every player. That condition reads as commentary on deck construction rather than a game state, because nothing else in the rules ever asks a player to count first initials mid-combat. The design inverts the usual relationship between cost and awareness: instead of spending resources to fire the sweep, you spend attention, watching the words on the board instead of the numbers. A table clogged with Goblins, a spread of identically named tokens, an alignment nobody planned can all set it off, so the trigger rewards observation over sequencing and punishes whoever stopped reading the type lines. Note that Bloodletter only feeds its own count when the shared letter happens to be 'B', so most of the time it is watching for a coincidence it cannot contribute to. It is a comedic mechanic that turns the act of reading permanents aloud into a live threat, wrapped around a fragile body: in effect a slow, conditional Pyroclasm that only pays out when someone at the table has been careless with their naming conventions.
