Brazen Blademaster

The threshold here is doing quiet, aggressive work: two artifacts on the battlefield turns a modest 2/3 into a 4/4 the moment it swings, and a 4/4 that attacks into most early boards without dying is a real clock for its cost. The condition is the interesting part, because it asks for a specific kind of deck. This is not a card that wants a single expensive artifact; it wants a low, wide artifact count, the sort of board where Treasure tokens, cheap equipment, and other artifact bodies accumulate as a byproduct of the game plan rather than a tax you pay to enable it. That places it in the aggressive-artifacts lineage red has circled for years: a beater whose payoff is conditional on the same clutter that powers everything else you are doing. The trigger checks on attack, not continuously, so the bonus is timed to combat and evaporates at end of turn, which keeps it pointed forward rather than defending. Its ceiling is modest and its floor is a 2/3 that trades poorly, but that spread is exactly the point of a common-rarity aggro payoff: it rewards a deck built to hit the artifact count consistently and does nothing special in one that cannot. As a raider whose muscle scales with the loot piling up around it, the design reads coherently with the Pirate subtheme it belongs to.
