@evouga I agree this is probably unplayable. Instant Speed Braingeyser is better than Braingeyser, but this card is almost always just worse than Stroke of Genius. Stroke only has one U in it's casting cost, making it easier to cast off of lots of artifact mana, and it can be used on your opponent to end the game in decks like High Tide. This card can't do either.
There is a corner case where this card is good, though, and that's where you want to dig in your deck deeply and put a particular card in the yard. I could see Worldgorger Dragon considering this card, for example. Mana Drain into this in a Dragon deck might legit end the game, since you can draw protection and possibly Animate dead, then bin the Dragon. At the same time, EOT pay UU to bin my Dragon to set up a win next turn is not horrible in a pinch, either.
Now, all we need is for Dragon to be good again
