Tribal Flames

Domain turned a cheap red burn spell into a payoff for greedy manabases, and this is the card that proved the mechanic could scale. The reward grows with the diversity of your basic land types, not the count of your lands, so the deckbuilding ask is precise: assemble a base that touches all five and the spell hits for a number no two-mana card has any business reaching. Three-color decks playing fetchlands and shocks can comfortably reach four or five, which is why this became the closer in piles built around five-color goodstuff. The design tension lives in the manabase rather than the spell itself: the rate is paid for entirely by how hard your lands work, and a mono-red deck holding this is staring at a one-damage misfire. That makes it a litmus test for a particular kind of deck, the one that bends over backward on fixing and wants a reason for all that strain to matter. Domain rewarded the strain. Where a burn spell normally caps its ceiling at the cost line, this one borrows its ceiling from a fully diversified base, which justified building a whole set's mechanic around the idea. It can erase a planeswalker, kill a blocker, or end the game from a respectable life total, and it asks only that your lands earned it.
