Dream Cache

Draw three, then hand two back: the math lands on a single net card, which tells you this was never really a draw spell. It is selection wearing a draw spell's clothes. The clause doing the work is the symmetry restriction. The two cards you return go both on top or both on the bottom, never one of each, so you cannot quietly bury a dead card on the bottom while parking a live one on top for next turn. Every cast forces a package decision instead of a clean fix. Bottom when your hand is already strong and you want fresh cards next draw step; top when you have just dug to two things you want and can only afford to keep one in hand now. That binary is the whole tension of the design, and it is what stops three-mana sorcery filtering from being a free engine. It reads like a draw spell and plays like Brainstorm with the safeties bolted shut, evidence that early blue card-smoothing was written with a far heavier hand than the cantrip-soaked decks that followed ever had to tolerate.
