Pox

The symmetry is the disguise. On paper this hits both players equally across four resources at once, but symmetric mass-destruction in Magic almost never plays symmetrically: it favors whoever set up to be hurt less. The deck built around it runs lean (few cards in hand, few creatures, a low land count) so that "a third of" rounds to almost nothing on its own side while it shreds an opponent's developed board, full grip, and built-up mana. That is the whole archetype: get under your own Pox, then drop it on a table that committed. The fractional, round-up structure is what makes the symmetry a lie, because the player with one card in hand discards one and the player with seven discards three. Pairing it with effects that punish empty hands and stranded lands, the kind of disruptive black control shell that wants the game stalled and starved, turns a card that reads like a board-wipe into a resource-denial lock. It asks every resource at once and trusts you to have already minimized your own exposure to each. The cost of three black pips, all the same color, is the price of permission to break the game's economy in your favor.
