Boom // Bust

The split-card frame from this era usually paired a cheap early play with an expensive haymaker; few are as lopsided as this, where both halves are land destruction at scales an order of magnitude apart. Boom names two lands on cast, one yours and one theirs, and its reputation rests on the fact that the symmetry is exploitable rather than locked. Aim the friendly half at a fetchland or any land you can sacrifice in response, crack that land before the spell resolves, and one of the two targets vanishes from the stack. Boom then resolves with only the opponent's land as a legal target: a trade that normally costs you a card and a land of your own to kill one of theirs becomes a free strike, your board untouched. Bust is the back end of the deal, a full Armageddon carried in hand for the price of running a split card you wanted anyway. Both halves are sorceries, which costs the card any ambush potential. Neither side can strand a tapped-out opponent on their own turn or shatter a combo at instant speed, and Bust flattens your own manabase alongside everyone else's, so a deck that detonates the back half has to be built to win through the rubble it makes. What the frame really sells is staged land destruction rather than a single decisive swing: pressure a manabase early with the cheap half, then, when the game refuses to end, level everything.
