Ultima, Origin of Oblivion

Land destruction has always split into two schools: blow the land up, or make it worse. This picks the second, and the mechanic is stranger than outright destruction. The blight counter does not remove the land; it hollows it out, stripping every type and ability and leaving a colorless tap-land that produces nothing the caster's opponent wants. Against a multicolor manabase, each attack effectively kills a color: dual lands shed their identities, and the victim keeps drawing spells they can no longer cast. Crucially, the counter lands on attack declaration, not on combat damage: a blocker or a chump does not stop it, so the flying body matters less for connecting than for surviving to swing again, since the trigger fires every turn the God attacks whether or not it gets through. The second ability closes the loop. Every land the controller taps for colorless yields double, so the gray rocks left in the opponent's hands are dead weight while the attacker's own colorless production compounds. Mana denial gets converted into a mana-advantage engine pointed in one direction. Where Sinkhole or Armageddon strike in a single blow, this one grinds a manabase into rubble one land per combat, and rewards a build that leaned on colorless production from the start. The denial and the ramp are the same clock, running against opposite ends of the board.
