Extract Power

Multiplayer theft dressed up as a windfall. The effect skims from every library at once, including your own, so a single-target top-of-deck steal it is not: you exile a card off each library and gain the right to play all of them, and every one but yours was somebody else's next draw. The look step is bookkeeping rather than a decision point (nothing here targets, and nothing lets you pick what leaves the top), but the peek still pays off, because you learn what cards you are about to hold before they turn face down, and you can sequence them with full knowledge. The face-down exile clause is what stretches the payoff across time. Because the cards stay exiled indefinitely and can be played without paying their costs, you are not locked into casting them this turn; you bank a hidden reserve of free plays and unload them as the board asks for them. That converts the sorcery from a burst of value into a slow-drip advantage engine, with the free-cast rider offering the chance to play something you could never otherwise afford. The color placement is the quiet tell: blue rarely gets to cast opponents' cards outright, and doing it at scale reads as the color reaching toward red's impulsive top-of-deck theft while keeping blue's foreknowledge intact. What it asks in return is a heavy six-mana price and the variance of whatever happens to be sitting on top of every library.
