City on Fire

Doubling damage is a known quantity: Furnace of Rath, Gratuitous Violence, Dictate of the Twins-adjacent effects have all offered the same 2x multiplier for years. Tripling it is the escalation, and the design squares the risk to match. Eight mana on a static enchantment that does nothing until you have a source dealing damage is a steep entry, so convoke is the pressure valve: the aggressive board you have already committed can tap to pay for the enchantment that turns their next swing lethal. That is the tension the card is built around. A red deck spilling creatures onto the battlefield is exactly the deck that can afford to convoke out an eight-drop a turn or two early, and exactly the deck whose combat damage benefits most from a 3x multiplier. The static line is deliberately broad: it reads "a source you control," not "creatures" or "combat damage," so burn, direct-damage triggers, and pings all get tripled alongside attackers. What keeps it from being a simple win-more piece is the sequencing question it forces. Because it multiplies rather than adds, it wants a board already capable of dealing damage before it resolves, and it demands you survive to the turn where the tripling actually lands. It is a payoff that asks you to have already built the engine it triples, then rewards you for having done so more violently than any doubler before it.
