Coastline Marauders

A 0/3 that does nothing until it swings, at which point it borrows its power from the wrong side of the table: the boost scales off the defending player's lands, so the fatter their manabase, the harder this Pirate lands. Trample is not decoration here; it is the delivery system, converting a swollen power number into damage a single blocker can only chip at. That inversion flips the usual aggro math. The card sputters against a mana-light opponent and turns lethal against a durdling ramp deck, so you are rewarded for pointing it at whoever looks best defended. Then there is Encore, which buys the corpse back from the graveyard and hands every opponent a hasty token copy sized against their own land base, all forced to attack, all cleared away once the turn ends. The two halves resolve into one idea the moment their alignment clicks: a creature whose power keys off enemy lands wants to aim copies at as many enemy land bases as it can reach at once. This is a multiplayer design through and through, where the same developed boards that make a table hard to break are exactly the fuel that makes this one connect.
