Break the Ice
Land destruction has always been color-pie awkward in black: it can shred a creature, a hand, or a life total, but breaking mana off the top belongs mostly to red and green. This one earns the effect by narrowing the target hard. It only hits lands that are snow or that could produce colorless, so it aims squarely at the two land categories most likely to be doing something the rest of the deck can't easily replicate: a snow manabase and colorless-producing utility or fixing lands. That target restriction is what makes the overload mode fair. Paying the full cost to change "target" to "each" doesn't turn this into a symmetrical Armageddon; it only sweeps the snow and colorless-producing lands on the table, leaving non-snow basics and ordinary duals intact. Against a deck built to abuse snow-matters payoffs or colorless-heavy fixing, that is a one-sided blowout; against a fair two-color basics deck, the overload does close to nothing. The design leans on a real structural insight: the lands worth destroying in black's colors are the ones a deck has deliberately assembled for a reason, so pricing the spell to punish exactly that construction gives it teeth without handing black a generic Stone Rain it was never supposed to have.
