Five mana, double-blue and a red, asks the format a real question: are you the deck that gets to cast this on curve, and is your sideboard deep enough to make the trigger worth the colored pips? In TMT, the answer is yes more often than the cost suggests. Fixing at common is good, hybrid commons like Mechanized Ninja Cavalry and Putrid Pals splash into UR shells without contortion, and the utility-land cycle (TCRI Building in particular) smooths a third color. The format is medium-speed midrange with a strong legendary payoff axis, which gives a 5/5 flyer at five room to land before the game has resolved.
UR Sneak is the natural home and treats this as a P1P2 or P1P3 ceiling, a hard floor at P1P5 when the deck is open. The trigger reshapes how you build the 40: you want a sideboard of one-of answers you would never maindeck, the situational Dimensional Exile against a Shredder, Unrelenting board, a second copy of Bot Bashing Time against go-wide, a Reach creature against a fliers mirror. Drafted without a wishboard plan, the trigger collapses into "draw a card," which is still fine on a 5/5 evasive body but underuses the slot.
Two real frictions. The double blue punishes greedy splashes; if your UR deck is really UR-plus-black-for-Stomped by the Foot, you cast this on turn six, not five. And the cast clause means Disappear is a feel-bad: blink it and you get the body, not the wish. Maindeck in any UR deck that resolves five mana. The grade reflects ceiling, not certainty.
