Desperate Castaways

A 2/3 for two mana in black is a perfectly playable body, which is exactly why the attack condition exists: the stats are paid for up front, and the artifact requirement is the rent the card pays for them. Pirates were built as the artifact-adjacent aggressive tribe, leaning on Treasure tokens to enable their attackers, and this is the clearest expression of that tax. A Treasure left over from an earlier turn, a cheap equipment, any artifact at all flips the switch and lets the body do its job. Without one, you have a 2/3 that blocks and waits. The design choice worth noting is that the restriction lands on attacking, not on the creature entering or surviving: it can still chump, still trade, still hold a flank, so the downside is conditional rather than crippling. That makes it a deckbuilding signal more than a combat liability, a common-rarity nudge toward keeping an artifact in play that a tribal aggro shell wants to do anyway. Strip the Pirates context and it is a vanilla beater with a footnote; inside a deck designed to manufacture Treasures on cue, the footnote is invisible.
