A-Tome Shredder

The graveyard is not usually a growth resource for a beatdown creature, and that inversion is the whole idea here. A hasty two-power body at normally trades in on attack and gets outclassed by turn four; this one converts the spent instants and sorceries piling up in your yard into permanent +1/+1 counters, so a spellslinger deck's natural byproduct becomes the fuel that keeps a cheap early threat relevant deep into the midgame. The tension is real: the ability is a tap, so counter and attack compete for the same turn, and every card exiled is a card denied to flashback, delve, or a graveyard-recursion plan you might rather leave intact. That opportunity cost pays for a rate that would otherwise be absurd, since the ability has no cap and asks only for cards you were spending anyway. The counters are the permanent kind, so the growth survives combat and end-step cleanups of temporary buffs, which matters for a creature meant to close games under pressure. It rewards a deck built to churn cheap spells rather than one that hoards them, a specific enough demand that this reads as a payoff piece rather than a generic curve-filler.
