Battle of Frost and Fire
A Saga that front-loads its power the way a sweeper does, then spends two more chapters trying to pay you back. Chapter one is the honest reason to run it: four damage to every non-Giant creature and every planeswalker is a sweeper stapled to a permanent that keeps ticking, and the Giant exemption is a flavor carve-out that doubles as a build-around, since a deck stocked with Giants walks away from its own board clear. The trouble is the two turns after. Scry 3 on chapter two smooths the draw but does nothing to the board, and chapter three asks for a specific behavior (casting a spell of mana value five or greater on that turn) before it hands over any card advantage, which means the payoff only lands if your curve is built to keep spending big when the Saga resolves its final counter. That conditional is the whole card's balancing act: the sweeper is unconditional and immediate, the reward is neither. The enchantment wants to be the opening of a plan rather than a reset button, sitting in a shell already leaning on expensive spells so chapter three has something to feed on. Absent that, you cleared the board as it entered and then paid two more chapters of setup you may never cash. The design is a wrap-around: erase the board now, reload only if you kept your hand heavy.
