Wu Warship
The geographic-grudge cycle this belongs to is one of the strangest design experiments in early-era development: a body whose entire restriction keys off your opponent's manabase rather than anything you do. A 3/3 for three with no evasion and no abilities would be unremarkable, but the clause turns it into a wager on the opposing land types. Against any deck without a single Island, this creature simply cannot enter the red zone; it sits as a blocker and nothing more. Against a blue shell, it attacks freely and demands an answer. So it is a conditional attacker whose offense is hostage to a deckbuilding choice the opponent already made, a creature that is either a beater or a wall depending entirely on the board across the table. The lineage runs through the older "hate" cards that punished particular land types, but most of those punished the controller of the land for owning it; this one inverts the logic, restricting its own bearer for the privilege of swinging. That inversion is what makes it a curiosity rather than a card: you pay full freight up front and cannot know, at the time you sleeve it, whether you have bought an attacker or a roadblock. The decision the card front-loads belongs entirely to your opponent, which is exactly backward from how a creature's combat utility usually gets decided.
