Armageddon for the symmetry-loving control player. Where the white original strands every land in the dirt permanently, this hands them back to their owners, which sounds gentler until you ask who profits from the reset. The answer is whoever spent the least to develop their board and whoever can rebuild fastest. Cast at the end of an opponent's turn, it bounces five-or-more lands back into hands that have already passed for the turn, forcing a full replay of the mana base one drop at a time while the caster has untapped and an open turn ahead. That asymmetry is the entire point: it converts a mass-bounce that reads as fair into a tempo windfall for the deck built to abuse it. The instant-speed clause is the load-bearing piece; Armageddon and its kin work at sorcery speed, telegraphing the reset and letting the opponent dump their hand first. Doing the same thing on the end step, after the opponent has committed, turns a board wipe into something closer to a Time Walk for lands. The reason it never became the staple Armageddon did is the same reason it is fascinating: returning lands rather than destroying them leaves the opponent with cards to recast, so the effect demands a follow-up to actually win, where the white version simply ends the game. It is land destruction reimagined as a tempo spell, and it asks a harder question of the deck around it.
