Purphoros, God of the Forge

The damage trigger is the whole reason this card has a constituency, and notice what it doesn't say: it fires whenever another creature you control enters, with no toughness floor, no power requirement, no caring whether the body is a 1/1 token or a hexproof bomb. That clause turns every go-wide engine into a clock and a burn spell at once. Flood the board with tokens and the table drains two at a time, indifferent to blockers and creature removal because the damage routes straight at faces. Lifegain is the real seam, not interaction on the board: a single Soul Warden on the other side, or a fat lifelink swing, can soak the math faster than you generate it, so the race is against opposing life-recursion as much as the clock. The triggers still go on the stack, so an opponent holding Stifle or Trickbind can clip one, but the trade is brutal: they spend a card to deny two damage off a single token, and you have a dozen more behind it. The God-frame devotion clause is the structural counterweight: until your red devotion reaches five it isn't a creature, so it sits out of range of creature removal and sweepers while the entry triggers keep firing the moment each new body resolves. You rarely need it to attack; the indestructible 6/5 is the upside, not the plan. And the team-wide pump is no afterthought: because it buffs every creature you control rather than itself, it converts a wide token board into lethal in a single attack step, exactly when the board is at its widest. This is a payoff that measures value in quantity, not quality: the question it asks is how many bodies you can manufacture, never how good any one of them is.
