Sokenzan Renegade

The drawback here is one of the strangest control-of-permanent mechanics the game has tried: keep your hand full and this 3/3 stays with you, but let an opponent out-draw you and it walks across the table to the player hoarding cards. It is a punisher card built backwards, rewarding full hands rather than punishing them, and it makes the creature a kind of social pressure valve. Empty your hand while an opponent holds cards and you risk handing them a body; keep the most cards yourself and the Renegade stays loyal. For a red deck willing to hold cards, the clause is nearly free, which is the whole point: this is a beater priced as a beater, with a downside that only bites the player who empties out first. The Mercenary creature type and the renegade flavor do real work, since a hired blade with no loyalty going to the highest bidder is exactly the fiction the rules text models. The Bushido 1 trigger sweetens the combat math, turning the 3/3 into a 4/4 the moment it blocks or gets blocked, so the card trades up in the brawls a hellbent deck wants to pick. It is a clean piece of color-pie discipline: red gets a cheap, efficient threat, and the cost of that efficiency is a leash that only tightens if you stop playing red's game.
