Audacious Swap

Removal that treats its target as a slot machine rather than a grave. Shuffling a nonenchantment permanent into its owner's library, then flipping the top card straight into play or onto the stack for free, is not clean interaction: it answers the problem in front of you while handing the opponent a random replacement, and lands come down without even a decision. That is the tension the card lives inside, and Casualty is what tilts it back toward you. Sacrifice a creature with power 2 or greater as you cast, and the spell copies with a fresh target, so a single instant peels two permanents off the board and inflicts two random top-of-library rolls at once. The design leans hard into variance as a feature: you are not denying the answer, you are betting that a shuffled-away threat is worth more than whatever the top of their deck coughs up. Because it hits any nonenchantment permanent at instant speed, the flexibility is real (it can strip a planeswalker, a bomb artifact, or a problematic land), but the free-cast rider means it plays best pointed at something whose replacement is likely to be worse than the thing you removed. It is removal for a table that would rather gamble than trade cleanly, and the Casualty copy turns a symmetrical coin-flip into two flips you chose to make.
