Gratuitous Violence

Doubling is one of the oldest levers red has for converting a small board into a lethal one, and this is the unconditional version: every point of damage your creatures deal, to anything, gets multiplied. The qualifiers red usually attaches to that kind of power are simply absent. There is no upkeep cost, no "only during your turn" clause, no "only in combat" restriction. A blocked attacker still doubles its damage to the blocker; a ping from a tapper doubles; a deathtouch creature still needs only one point, but everything else scales. The cost is the color commitment, which is the real tax: triple red on a five-mana enchantment that asks you to already have threats on the board before it does any work, then folds to any disenchant. That sequencing demand is the friction the rate buys, and it keeps the card in dedicated aggressive shells rather than functioning as a generic value piece. Damage doubling lives squarely in red's slice of the pie; this is the broadest grant of it, indifferent to whether the damage is combat, direct, or incidental, asking only that one of your creatures be the source. Read the line carefully, though: it doubles damage, not life loss, so drain and life-payment effects pass through untouched. Stack a second copy and the multiplication compounds, turning a single connecting attacker into a finisher.
