Bolt of Keranos

The price for the scry is exactly one mana over rate and one rung down the speed ladder. Three damage to any target is the figure red has been measured against since the beginning, and the long parade of "Bolt at a premium" designs, Lightning Strike at two, Searing Spear before it, all hover near that baseline. This one pays its third mana not for flexibility but for a sliver of card selection: scry 1 stapled to the back end, letting a stranded late-game removal spell double as a peek at the next threat or land, or a way to bottom a dead draw. Sorcery speed is the heavier tax than the converted cost. You cannot hold it up as a combat trick or an end-step play, so the scry has to claw back the tempo you concede by committing a turn early and tipping your hand. It is a deliberately unexciting rate by burn standards, built for a deck that wants its removal to do a little smoothing on the turns it has nothing worth killing. The lineage is the long line of red sorcery-speed burn that trades raw efficiency for a rider; here the rider is the cheapest, most reliable filtering red owns, glued to the most familiar damage number in the color.
