Ranked most-played first, the best damage doublers in Commander are Twinflame Tyrant; Fiery Emancipation; Solphim, Mayhem Dominus; City on Fire; and Gisela, Blade of Goldnight. Every card on this list is legal in Commander as of the card data dated November 11, 2026.
A damage doubler is a replacement effect: if a source would deal damage, it deals double that damage instead. Furnace of Rath and Dictate of the Twin Gods double all damage, Angrath's Marauders only your sources, Gratuitous Violence only your creatures, and Fiery Emancipation and City on Fire triple it. Burn, combat and commander damage decks play them to end the game in one turn.
They differ in whose damage they multiply and against whom. Twinflame Tyrant and Solphim, Mayhem Dominus double only what you deal to opponents and their permanents (Solphim only noncombat damage), Fire Servant only your red instants and sorceries, and Inquisitor's Flail and The Sound of Drums one creature's combat damage. Furnace of Rath and Dictate of the Twin Gods double damage dealt to you as well.
Rules note: two damage doublers stack, because each replacement effect applies once to the same event, so two of them make four times the damage. When several apply, the player being dealt the damage, or the controller of the permanent, chooses the order.

Commander-legal cards with a replacement effect that makes a source deal double, twice or three times the damage it would deal, to any permanent or player or to the ones it names: your sources, a creature type, an equipped or enchanted creature, or every source. Cards that multiply only their own damage, or only damage dealt to you, and spells that deal a doubled amount once are not listed. One entry per card, most-played first.

A card that makes a source deal more damage than it would. Each one does it with a replacement effect (rule 614.1a: effects that use the word "instead" are replacement effects): if a source would deal damage, it deals double that damage instead (rule 701.10g). The damage is dealt once, at the larger amount, and its results, such as life loss, follow it (rule 120.3a).
Yes. A replacement effect gets only one opportunity to affect an event (rule 614.5), but each doubler is a separate effect: once one has been applied, the next one applies to the modified event (rule 616.1f). Two doublers make four times the damage, a doubler and a tripler six times. When several apply, the affected player, or the controller of the affected permanent, chooses the order (rule 616.1).
Yes. A player who has been dealt 21 or more combat damage by the same commander over the game loses (rule 903.10a), and what counts is the damage actually dealt, after replacement effects (rule 120.4b). A commander whose 11 combat damage to a player is doubled deals 22, enough on its own.
