Lost in Space

Bounce that returns a permanent to the library rather than the hand trades a clean tempo answer for a different one: instead of handing a threat back to be recast next turn, it buries the thing under a full turn's worth of draws, or, if the owner tops it, forces them to spend their next draw step reclaiming it. The catch built into every effect of this kind is that the owner picks top or bottom, not the caster, which is what keeps the rate from being a hard removal spell at instant speed. Top means the permanent survives but eats a draw; bottom means it is gone for the game barring a shuffle, at the cost of drawing something new instead. Either branch buys the caster a turn against a mana rock, an equipment, a fresh artifact, or a creature, and reaching artifacts as well as creatures widens the target pool past a plain creature bounce. The surveil rider is a single look, not an engine: one filtered draw stapled to the answer, worth exactly one card's worth of selection while the opponent sorts out the permanent you just displaced. It is a control-shell tempo tool for decks that want to answer a permanent without answering it permanently, banking a small selection edge on the way rather than committing to a kill.
