Wirecat

A 4/3 for four generic is an aggressive body, and the card buys that rate by chaining its own combat readiness to the absence of a card type: this cat seizes up, unable to attack or block, the instant any enchantment touches the battlefield, regardless of who controls it. That symmetry is what makes the design so peculiar. It is not a hate piece against enchantments; it is a beater that gets hated out by them, and the cruel part is that the check is global. An opponent can switch off your attacker by resolving a single aura or global enchantment of any kind, and you can brick the cat yourself by playing one. White and green were the enchantment-saturated colors of its era, so a colorless body whose on switch is an empty enchantment zone was structurally soft against exactly the strategies that leaned on auras and pillowfort permanents. The flavor renders the mechanic literally: a clockwork cat that freezes around magical wards, drawing its motion from a world scrubbed clean of enchantment. It belongs to a period when colorless cards were allowed to stake out positions in the color pie, though the position here is one of vulnerability rather than strength, a four-drop that goes quieter the more spellcraft fills the board, asking you to maintain a board state you only ever half control.
