Scroll Rack

A card-quality engine that pretends to be card advantage and is something stranger: it converts cards you don't want into cards you've chosen, without ever changing the size of your hand. The trick is the sequencing. You exile excess from your hand, put an equal number from the top into your hand, and only then arrange what you exiled back onto your library. That ordering clause is the whole card. Every shuffle effect, every fetch, every Sylvan Library or Sensei's Divining Top loop becomes a filter, because the rack lets you stash your dead draws on top and then wash them away with a single shuffle. It does not draw you cards; it launders them. Each activation costs one mana and a tap, so the engine wants to be run repeatedly across a game rather than burst all at once, and the limitation is built into that loop: without a shuffle, the cards you bury on top are exactly the cards you draw back next turn, so the rack only converts a clogged hand into a better one once a reshuffle arrives from somewhere in your deck. The detour through the top of your library also dodges hand disruption: cards you tuck away are no longer in your hand by the time an opponent's discard resolves. It is a tools-for-the-toolbox artifact in the oldest sense, a piece that quietly turns the top of your library into a resource you control rather than one you gamble on.
