Torture

A repeatable shrink-ray bolted to an Aura frame, and a fossil of an era when this was considered a reasonable rate. Most removal that kills a creature does it once and walks away; this commits a permanent to the board and then charges two mana per activation to grind the target down a point at a time. Because the ability is an open mana sink rather than a once-per-turn tick, a creature dies the instant you have enough mana to bury it in counters in a single turn, but most of the time it operates as a slow drip you pay across several turns. The trade is permanence for tempo: the engine never runs out, but it costs a card up front, and it does nothing to a creature you cannot afford to feed it on the turn it matters. Shrinking with -1/-1 counters rather than a static -X/-X is the quietly interesting part of the build, since the counters stay on the body even if the Aura leaves and stack with anything else chipping at the same creature. The design lineage that descended from this idea (slow, attrition-based creature removal that prices itself in mana rather than cards) ran through cleaner executions later, but the kernel is here: removal as a faucet instead of a switch.
