Atsushi, the Blazing Sky

Red aggro's oldest problem is that its threats stop mattering the moment they leave the battlefield: trade off, get chumped, eat a removal spell, and the tempo you invested evaporates. This 4/4 flyer answers that with a death trigger that refuses to let the investment die with the body. The choice is what makes it resilient rather than merely good: three Treasure tokens turn a dead Dragon into a full turn of ramp or fixing, while exiling the top two cards to play them buys back the card advantage red normally cannot recover. Neither mode is loose. The card-advantage half runs on a clock, playable only until the end of your next turn, so it rewards a curve fast enough to spend what it digs up rather than hoarding it. The Treasure half is unconditional value that happens to accelerate exactly the kind of expensive spell a beatdown deck struggles to reach. Because both payoffs fire on death rather than on cast or attack, the card wants to be traded, blocked, or removed: it is a threat that punishes the natural responses to a threat. That inversion is the whole design. Where most aggressive Dragons ask the opponent to find an answer, this one makes finding the answer part of the cost, and leaves the red player choosing between refueling the hand and refueling the mana on the way out.
