Amphin Cutthroat

The 2/4 body is the defensive blue common stripped to its skeleton: it wins no races, but the four toughness is the number doing all the work. That single point over a 2/3 is what separates a wall that survives the early burn and combat trick from one that dies to it, and it is precisely the threshold a controlling deck needs to climb under while it assembles its late game. A creature like this exists to give a slow blue strategy permission to be patient: it concedes tempo deliberately, forcing the aggressor to overcommit bodies before the game tips toward the long-game player. It blocks, it holds, and it does nothing else, which is the entire brief. The Rogue half of the type line is incidental; the Salamander is the part that registers. As filler goes, it makes no pretense otherwise: priced to be unexciting, shaped to do one job, and unambiguous about which side of the combat math it lives on, the toughness sitting in front of the power on purpose.
