Sarkhan's Unsealing

Most enchantments that reward casting big creatures want you to commit to a single haymaker; this one builds two damage tiers into the trigger, and the gap between them is the whole design argument. Power 4 to 6 buys a four-damage bolt at any target, the kind of body most red and green midrange decks already run as a curve-topper, so the cheap mode comes online without bending the deck. Power 7 or greater turns the same enchantment into a one-sided sweeper aimed at an opponent's board and their planeswalkers, so the payoff scales with how greedy your top end is. What keeps the tiers honest is that they fire on cast, not on entry: the damage resolves whether or not the creature sticks, so removal pointed at your threat does nothing to stop the burn already on the stack. That timing also means every qualifying spell is its own trigger, so a curve that chains multiple qualifying bodies compounds the damage rather than betting everything on one finisher. The lineage is red's long habit of converting big-creature commitments into raw damage, the same instinct behind Warstorm Surge and Where Ancients Tread. This design moves the reward to the moment of casting and steepens it as the creatures get bigger. The seven-power tier is the ceiling, and it is the part that turns a value engine into a board-clearing finisher: four to the face, four to every creature and planeswalker across the table, all off one spell you were already going to cast.
