Tahngarth's Glare

Most one-mana red sorceries point at a face or a board. This one rearranges information instead: you see and reorder your opponent's next three draws, they do the same to yours, and nothing leaves either library. The symmetry is the whole problem. Giving an opponent a free hand to reorder your top three is rarely something you want for its own sake, so the card only pays for its mana when arranging their draws matters more than they could ever leverage arranging yours: foreseeing a lethal swing, sequencing around a removal spell you can now confirm is coming, or stacking their library to deny a topdeck after a fetch or shuffle has reset it. The mirror is what makes it a hard sell, not a cantrip-with-extras. There is no advantage on the rate sheet; the advantage is entirely in who can act on what they arrange, and the design refuses to hand you a one-sided peek the way Telepathy or a scry effect would. It is built for the player who treats the top of the library as terrain worth fighting over and who is comfortable being manipulated in exchange for manipulating. That comfort, not the cost, is the transaction. The price of stacking is being stacked, and the card is only worth casting in the rare spot where that exchange is lopsided in your favor.
