Invert the Skies

Most modal spells let you read both lines and pick one when the spell goes on the stack; this one folds the choice into the mana you tap, so the decision happens as you reach into your pool rather than after announcing the cast. Spend green and your opponents' fliers crash to the ground; spend blue and your own team takes to the air; spend both and you do everything at once, opening a clogged board to a one-sided aerial swing. That branching cost is the design idea worth lingering on: a two-color deck always has the full split available, while a deck leaning on a single color gets the narrower half at the same four mana. The blue mode is a finisher enabler, granting evasion to push damage over a stalled ground. The green mode is the inverse, dropping attacking fliers into reach of your blockers or stripping defenders so your own fliers sail past. Cast at instant speed, either reads as a combat trick: green ambushes a planned aerial attack, blue lifts your creatures over a planned block. It is an early experiment in using hybrid as a logic gate rather than a cost-saver, the pips functioning as a switch that selects which half of the spell resolves, and that structure has aged better than the raw rate suggests.
