Reckless Barbarian

Sacrifice for : the numbers wash out, since you paid to cast it and get two red back on demand. What that even exchange buys is a delay. Cast now, redeem the mana when the color actually matters, and in between a 2/2 stands on the board to attack, block, or wait for a payoff that cares about creatures dying. Two jobs collapse into one two-drop. It is an early aggressor that converts to fuel once the ground gums up, and it is a mana source that has already handed a sacrifice engine its death trigger by the time it cashes out. Red decks built to treat their own creatures as spendable resources get double duty from a single slot. The genuine curiosity lives on the type line: a creature engineered to be thrown away still counts as a Dragon, so dragon-matters effects that would never expect to reward disposable fodder reward this one. That interaction is the least practical thing about the card and the most amusing. The real appeal is how tidily a creature and a self-redeeming ritual fold into the same package.
