Every Card That Doubles Triggered Abilities, Ranked: Krang Leads the Way

If you're trying to figure out which cards actually double triggered abilities in Commander and which ones are worth slotting into your builds, Cooper Gottfried at EDHREC has done the heavy lifting: a ranked list of all 34 cards in the category, timed to the arrival of Krang, the All-Powerful, the Teenage Mutant Ninja Turtles Utrom Robot that doubles draw triggers and is already turning heads in Wheels-based strategies.

Before getting into the rankings, a quick mechanical note worth internalizing: ability doublers are cards that copy or double a triggered or activated ability on the stack. That definition deliberately excludes Doubling Season and Anointed Procession, which don't copy a triggered or activated ability but instead modify how permanents enter or how tokens are created. That distinction matters when you're building, because these 34 cards interact with your deck in a fundamentally different way than those staples do.

The EDHREC ranking groups similar cards together where applicable, because as Gottfried notes, it's hard to decouple trigger doublers that affect the game in the same way. Here's where every card lands.

1. Elesh Norn, Mother of Machines

Sitting at rank 3 on the EDHREC list, Elesh Norn is one of the most powerful trigger doublers in the format. Her broad doubling of your own enters-the-battlefield triggers, combined with shutting off opponents' ETB effects, makes her a two-for-one staple in competitive and high-power Commander tables.

2. (Rank 4-21 grouping: Top-tier ETB and general trigger doublers)

The EDHREC article groups a large cluster of high-impact doublers together in the upper rankings because their effects are difficult to disentangle. These cards represent the format's most broadly applicable trigger-doubling effects, covering ETB, combat, and other recurrent triggers that show up across the widest variety of Commander decks.

3. Veyran, Voice of Duality

Draftsim ranks Veyran at #8 on their independent list of ability doublers, recognizing the card's power in spell-slinging builds that chain instants and sorceries. Veyran doubles triggered abilities you control that trigger from casting or copying spells, which makes it a natural engine piece in Izzet storm-adjacent strategies.

4. Weaver of Harmony

Draftsim places Weaver of Harmony at #9. It sees play in enchantment-focused decks where buffing your enchantment creatures is already a priority, and it occasionally doubles triggers from cards like Spirited Companion and Ossification, turning modest value into compounding advantage.

5. Teysa Karlov

Ranked #10 by Draftsim, Teysa Karlov is one of the best aristocrat commanders in the format. Every creature death triggers every death-care card you control twice, including the death trigger of the creature that just died: if Doomed Traveler dies under Teysa, you get two 2/2 Spirit tokens, and if Blood Artist is on the battlefield, you're lifedrainingan opponent twice per creature lost.

6. Ashnod the Uncaring

Draftsim ranks Ashnod at #11, and understanding the difference between Ashnod and Teysa Karlov is critical for builders. Ashnod doubles only the activated ability that sacrificed a permanent, not the death trigger of that permanent, which makes it a narrower but still powerful piece in sacrifice-activation builds rather than pure aristocrat shells.

7. Felix Five-Boots

EDHREC places Felix Five-Boots at rank 22. Felix is the face of ETB doubling in the lower-ranked tier, representing a whole category of cards that double abilities triggered when creatures deal combat damage to opponents. You can double the cards you draw or the cards opponents discard, among other saboteur payoffs, making Felix especially potent in aggressive creature strategies.

8. (ETB doubler group: Starfield Vocalist and similar)

The EDHREC commentary for Felix's tier notes that ETB and combat-damage doublers are "where most people's minds go" when thinking about trigger doublers. Commander staples like Quantum Riddler, Gray Merchant of Asphodel, and Imperial Recruiter all carry ETB triggers that become backbreaking when doubled. Newer prints like Starfield Vocalist demonstrate that Wizards of the Coast is still actively exploring this design space.

9. Krang, the All-Powerful

EDHREC ranks Krang at #23, one slot below Felix Five-Boots, but the reason this Teenage Mutant Ninja Turtles card is reshaping conversations about Commander construction is its specificity: Krang doubles draw triggers, which interacts with a completely different cluster of cards than ETB doublers do. Blue is the best color for drawing cards, which benefits Krang greatly, and the prevalence of cards that care about players drawing more than one card per turn, like Faerie Mastermind and Orcish Bowmasters, means Krang enters a rich ecosystem of payoffs. Krang even accelerates win conditions like Psychosis Crawler, and Gottfried expects this Utrom Robot to find a home in Wheels decks as a payoff for all the cards being drawn by all players.

10. (Scrap Trawler synergy tier)

One of the more niche but exciting applications noted by EDHREC: a trigger doubler that makes Scrap Trawler into an even better card. The commentary is direct about it: "As if it needed any help." Scrap Trawler's artifact-death recursion triggers are already among the more powerful recursive loops in artifact-based Commander strategies, and pairing it with a trigger doubler creates compounding value chains that can be difficult for opponents to interrupt.

11. (Mid-tier doublers: Ranks 24-32)

The middle and lower-middle section of the EDHREC list covers doublers that are more situational or tied to narrower archetypes. These cards aren't format-warping, but each one does meaningful work in the right shell, particularly in decks that have been built to maximize a specific trigger type that happens to fall in this range.

12. Hama Pashar, Ruin Seeker

EDHREC ranks Hama Pashar jointly at 33-34 alongside Dungeon Delver. Hama Pashar doubles dungeon room abilities, which Draftsim identifies as the defining mechanical function placing it in the ability doubler category at all. The ceiling exists: getting two triggers off the last room of Dunercity feels great, but a lot of setup is required to get there, and dungeon progression is among the more resource-intensive paths to a doubling payoff in Commander.

13. Dungeon Delver

Paired with Hama Pashar at ranks 33-34, Dungeon Delver sits at the absolute bottom of the EDHREC list for the same fundamental reason: dungeon triggers, while genuinely fun game pieces in Commander, are far from the strongest thing that can be doubled in the format. The setup cost to reach the high-value rooms consistently just doesn't compete with the immediacy of ETB doublers, death-trigger doublers, or draw-trigger doublers operating higher on the list.

The core takeaway from this 34-card survey is that trigger doublers are only as powerful as the triggers they're doubling. Elesh Norn's broad ETB doubling earns its top-three placement because ETB triggers are everywhere in Commander. Krang sits at #23 not because doubling draw triggers is weak, but because the draw-trigger ecosystem, while growing fast with cards like Faerie Mastermind and Orcish Bowmasters rising in prevalence, is still narrower than the ETB space. Hama Pashar and Dungeon Delver park at the bottom because dungeon room triggers, however satisfying to fire off twice, require too much investment to generate competitive returns.

The more interesting implication is the long game: as Wheels strategies accumulate more payoffs and draw-care cards continue to be printed, the ceiling for Krang rises. A trigger doubler's ranking today is partly a snapshot of the current card pool, and the current card pool is increasingly kind to blue draw synergies.
