Biblioplex Tomekeeper

The prepared mechanic poses a strange question of the board: which creatures are armed, and does an opponent get a say in it? This construct is the toolbox answer. It carries no prepare spell of its own; its whole reason for existing is to reach into the state that other cards create, flipping a creature into prepared so it can fire off its readied effect ahead of schedule, or stripping prepared status from an opposing threat before it can cash in. That second mode is the one worth dwelling on, because most mechanics that reward a stored resource have no built-in way to be denied. A saga ticks forward whether you like it or not, an emblem sits permanent and untouchable, most counters answer only to narrow dedicated removal; prepared, by contrast, hands a control lever to whoever draws this body. The enters trigger reads "up to one," which is the design's honest concession: with no target worth touching, the Tomekeeper simply does nothing but present a 3/4, and the ability was never meant to be a value engine on a bare board. Its ceiling belongs to a deck already committed to prepare spells, where it becomes a two-way interaction: an accelerant for your own readied payoffs and a reset button aimed at an opponent's. Absent that support, it is a 3/4 that trades in combat and chooses nothing worth choosing.
