Rose, Cutthroat Raider

Junk is the mechanic worth reading here, and this card is the piece built to abuse it hardest. Most Junk producers hand you one token as a consolation prize attached to some other line of play; a wide attack turns this into a manufacturing line, since the raid trigger scales the tokens off how many opponents you declared an attack against, not how big the attack was or whether it landed. Declaring the attack is enough, which already tilts the design toward multiplayer tables where there are more opponents to point creatures at. The second ability is what closes the loop: every Junk you crack for its impulse-draw generates a red mana on the way out, so the engine that just handed you cards immediately hands you the mana to spend them. The tension the designers had to manage is that impulse draw punishes hoarding: a Junk exiles a card you must play that turn or lose it, so the mana it produces is only worth anything if you convert it into action before the window shuts. That timing pressure keeps the flywheel from being free ramp. The mana comes with a use-it-now clock attached, which rewards a deck built to cash a sudden burst of red into immediate plays rather than bank it. The first-strike body and the attack-triggered tokens both point at the same aggressive, do-it-this-turn posture the sacrifice payoff demands.
