Sphere of Annihilation
The delayed one-sided sweeper that isn't one-sided at all. What separates this from the usual scaling wraths is the calendar it runs on: nothing happens the turn it lands. The X void counters are set on entry, and the exile only fires on your next upkeep, which means every opponent gets a full turn of foreknowledge about exactly which mana values are about to disappear. That telegraph is the entire cost of the effect. A player facing it can commit only creatures above the threshold, hold priority nowhere useful, or simply race the clock before the sphere goes off. The graveyard clause is the quieter half and the more distinctive one: it doesn't just clear the board, it exiles matching creature and planeswalker cards out of every graveyard too, so reanimator and recursion plans lose their fuel on the same trigger that wipes the field. Two design choices keep it honest and symmetric. It exiles rather than destroys, dodging indestructible and death-triggers alike, but it never spares its own controller, so building around it means keeping your threats above the water line you set. The named theme is drawn straight from the collapsing gravity-sphere of its source material, and the mechanic follows the fiction cleanly: a fixed radius of destruction that pulls in everything small enough, announced a turn before it consumes the table.
