Red Sun's Zenith

Most X-burn spells are a one-and-done transaction: pay the mana, point the damage, watch the card hit the graveyard. The shuffle clause rewrites that math entirely. A scaling burn spell that returns to your library is a renewable resource, which turns the late game into a question of whether you can keep finding it rather than how many copies you can draw. Paired with that recursion is an exile rider: damage that would kill a creature removes it from the game instead, sidestepping recursion and the death triggers that punish ordinary burn. That combination makes the card a finisher and an attrition engine at once, a removal spell early and an inevitable source of reach once the board has stabilized. The trade-off is real and built into the cost: shuffling a copy back thickens your library and dilutes future draws, so reusability comes packaged with the worst conversion rate in burn, since one mana of the cost buys nothing but the red commitment. This belonged to a five-spell cycle, one per color, each scaling on X and each shuffling back, with the colors splitting the labor along familiar lines: where the white version reanimated and the green version ramped, red took the obvious job of pointing damage anywhere it liked, permanently.
