Purphoros, Bronze-Blooded

Every Theros god carries the same devotion clause, and every other one leans the same direction: cross the threshold, get the body. This one flips the incentive without touching the mechanic. The 7/6 indestructible beater is the least interesting thing here, because the two abilities that matter (the haste anthem and the pay-to-cheat-a-creature engine) work whether or not devotion to red has hit five. So the optimal posture is often to sit below the threshold, leaving a static engine on the board as a noncreature enchantment, immune to every piece of creature removal your opponent is holding. The activated ability is the payload: a Sneak Attack effect that drops a red or artifact creature straight from hand onto the battlefield with haste already granted by the anthem. The end-step sacrifice is what prices it: absent a way to profit from the creature on the way out, each activation is a one-turn rental. That constraint is also the deckbuilding prompt. Point it at a single enormous threat and you get an alpha strike that vanishes; point it at something with an enter-the-battlefield trigger, or a creature whose death you can bank with an aristocrat effect, and the rental starts paying dividends every turn. The design's quiet trick is that it plays best when the God stays a mere enchantment: the card rewards you for never crossing the threshold that would wake its own body up.
