Reanimation built as a coin flip, and an instructive one: the spell that wants you to fill your graveyard with creatures and only creatures. The randomness is doing all the design work here. You reorder the yard at random and then hand the choice of which card to grab to an opponent, who is choosing blind because the order they're picking from is itself randomized. The result is a probability dial rather than a tutor: load the graveyard with twenty creatures and one noncreature, and the odds are nearly all upside; run a balanced graveyard and you are exiling your business spells half the time. That gap between worst-case and best-case construction is what the card is actually about, and it sits squarely in an era fond of attaching steep, fiddly costs to effects other designs handed out clean. Compare the straightforward reanimation of the time, where you picked the target and paid in life or discard; this asks you to engineer the entire contents of your graveyard so that "random" stops mattering. The exile clause is the punishment for sloppiness: a missed flip doesn't just whiff, it permanently removes the card, so the spell rewards a deck that has done the work to make its graveyard a creature-only pool before it ever gets cast.
