Atsushi, the Blazing Sky lets a red deck choose what kind of resource its dying Dragon should leave behind. One mode creates three Treasures; the other exiles the top two cards and lets you play them until the end of your next turn. Flying and trample give the four-mana creature a credible combat role before that choice becomes necessary.
The Treasure mode is useful when you already have action in hand and need mana to deploy it. The card-access mode is better when your hand is running short, although you still pay spell costs and follow normal land-play limits and timing. A land among the exiled cards can be played only if you have an available land play during the allowed window.
Sacrifice outlets let you choose the timing rather than waiting for removal or combat. Ashnod's Altar can add mana alongside the chosen death reward, while Goblin Bombardment can convert the body into damage. In a deck with black, reanimation can repeat the exchange; in a Dragon deck, Atsushi also contributes to the creature type plan at a relatively accessible cost. The main protection concern is how it leaves the battlefield: exile and bounce bypass the death trigger. If the stored value matters, keep a sacrifice route available and choose the mode based on the next turn's actual needs, not simply the larger-looking immediate reward.
