Sinister Waltz
Most reanimation spells offer a clean transaction: pick your target, pay the cost, watch it land. This one prices two bodies at once by refusing to let you keep all three picks. You name three creatures in the graveyard, get two back, and lose the third to the bottom of your library, with the randomizer deciding which two arrive. For any single card you care about, that math is two-in-three: better than a coin flip, but not a guarantee, which matters when the whole plan hinges on one specific creature returning. The design wants the opposite of that. It rewards a graveyard stocked with interchangeable value creatures, where any two of your three picks is a fine outcome, rather than the single stacked haymaker that classic single-target reanimation rewards. The bottom-of-library clause is the quieter cost: the loser is not exiled or shuffled back but buried under your whole deck, so recovering it takes real time. As a one-shot at five mana returning two creatures, it trades the precision of targeted reanimation for raw bodies-per-cast, and asks you to build a board deep enough that the randomness never stings. Get the composition right and every result is acceptable; lean on one irreplaceable finisher and the variance becomes a real tax rather than a rounding error.
