Tome Shredder

A red beater that mines the graveyard for growth: each activation banishes an instant or sorcery already sitting in the yard to add a +1/+1 counter, turning the discard pile of a spells-matter deck into permanent stats. The wrinkle is that this is a sink for cards that have already done their job, not a card that wants you to hoard them. Haste gets the body attacking the turn it lands, but the growth mechanism runs through the same tap the attack does, so every counter is a turn spent growing rather than swinging. That tension defines it: exile is permanent, so each counter spends a card you might have wanted to flash back, buy back, or otherwise reuse, and the ability competes with combat for the creature's tap. It is a mana-light way to give a spellslinger deck a proactive clock, sitting in the same conceptual lineage as red's other graveyard-fed grinders, but priced and bodied as a role-player rather than a centerpiece. The reward scales with how many spells you cast and how little you need them afterward, which makes it a barometer for whether your deck is willing to trade recursion for board presence.
