Meta description: Every 2-card infinite combo in Commander, sorted by color identity. Thoracle, Kiki-Jiki, Heliod, and the rest of the best two-card kills.
The case for two cards
A three-card combo is a deck that wins when nothing goes wrong. A two-card combo is a deck that wins through interaction.
That's the trade. Every additional card in your win condition is another card your opponents can counter, kill, or steal. Every prerequisite (mana threshold, graveyard state, board count) is another way the line falls apart. The decks at the top of competitive Commander run two-card kills not because they're flashier, but because they survive.
This is the working list — every two-card combo worth knowing, organized by color identity. Most are in active tournament play right now. A few are slower but matter for casual builds. The split is called out where it matters.
Quick answer
The strongest two-card combos in Commander are Thassa's Oracle + Demonic Consultation (UB win-the-game), Kiki-Jiki + Zealous Conscripts (R infinite hasty creatures), Heliod + Walking Ballista (W infinite damage), Devoted Druid + Vizier of Remedies (GW infinite green mana), Isochron Scepter + Dramatic Reversal (U infinite mana with rocks), and Exquisite Blood + Sanguine Bond (WB win-the-game). Most cEDH decks run at least one of these as a primary win line.
How to read this list
Each combo notes the color identity, what it produces, and any "trivial prerequisite" — meaning a small condition (mana available, counter on a creature) that's almost always met by the time you assemble the combo. A two-card combo that requires "five lands untapped" is still a two-card combo at the table. One that requires "a sacrifice outlet" is a three-card combo dressed up.
The complete combo database is bigger than what fits here. To audit your specific list, the combo analyzer parses your decklist against every known combo on Commander Spellbook and surfaces what you actually have.
Win-the-game combos
These end the game on resolution. No additional card needed, no follow-up turn required.
| Combo | Colors | How it wins |
|---|---|---|
| Thassa's Oracle + Demonic Consultation | UB | Cast Consult naming a card not in your deck. Library is exiled. Oracle ETB checks your library — empty — you win. |
| Thassa's Oracle + Tainted Pact | UB | Pact exiles your deck unless you reveal duplicate names. Built around a singleton mana base. Oracle does the rest. |
| Laboratory Maniac + Demonic Consultation | UB | Older version of the Thoracle line. Lab Man can be killed in response, so most decks use Oracle now. |
| Jace, Wielder of Mysteries + Demonic Consultation | UB | Same idea, Jace's emblem version. Used as a backup when Oracle is exiled. |
| Exquisite Blood + Sanguine Bond | WB | Any starting life-loss or life-gain triggers a chain that drains opponents to zero. |
| Exquisite Blood + Vito, Thorn of the Dusk Rose | WB | Same loop, Vito as the second piece, often easier to tutor. |
The Oracle line is the most-played two-card combo in cEDH for a reason. It's compact, mana-efficient, and tutorable from any spot. Decks built around it generally run multiple instances of the second piece (Consultation and Pact) for redundancy.
Infinite damage combos
These produce unbounded damage on the same turn they assemble. Ends the game given any open opponent.
| Combo | Colors | Notes |
|---|---|---|
| Heliod, Sun-Crowned + Walking Ballista | W | Ballista needs 2+ counters. Heliod gives Ballista lifelink. Shoot, gain life, Heliod replaces the counter. Loop. |
| Niv-Mizzet, Parun + Curiosity | UR | Niv pings on draw. Curiosity draws on damage. Endless feedback loop. |
| Niv-Mizzet, Parun + Tandem Lookout | UR | Same loop with soulbond instead of an aura. |
| Niv-Mizzet, Parun + Ophidian Eye | UR | Triplet of the same effect. Pick one for redundancy. |
Heliod + Ballista needs at least two +1/+1 counters on Ballista at the start, which usually means casting Ballista for X=2 (a four-mana investment) or pumping it via Heliod's static. The combo is famously slow on assembly — six total mana — but the ceiling is "I cast Heliod into a Ballista and the table dies."
Infinite hasty creatures
These don't kill on the spot, but produce so many haste creatures that the next combat step ends the game.
| Combo | Colors | Notes |
|---|---|---|
| Kiki-Jiki, Mirror Breaker + Zealous Conscripts | R | Kiki copies Conscripts. Conscripts ETB untaps Kiki. Repeat. |
| Splinter Twin + Zealous Conscripts | UR | Twin enchants Conscripts. Tap to make a token. Token untaps original. |
| Splinter Twin + Deceiver Exarch | UR | Same, Exarch as the untapper. Cheaper to assemble. |
| Splinter Twin + Pestermite | UR | Same, with flying. |
The Kiki-Jiki line is the engine for most red-based cEDH combo decks (Magda, Godo, Krenko-as-99). Twin lines are popular in Izzet shells where Twin can also be tutored as an enchantment.
Infinite triggers
These produce infinite ETB/LTB/death triggers without directly winning. They win when paired with any aristocrat effect (Blood Artist, Zulaport Cutthroat, Impact Tremors) already in the deck.
| Combo | Colors | Output |
|---|---|---|
| Mikaeus, the Unhallowed + Walking Ballista | B | Ballista shoots itself, dies, undying brings it back, repeat. |
| Worldgorger Dragon + Animate Dead | B | Animate brings Dragon back, Dragon exiles permanents, Animate falls off, Dragon dies, permanents return, loop. |
The Mikaeus + Ballista line is a common point of confusion. By itself, it doesn't deal infinite damage — Ballista's ping kills itself instead of an opponent because Mikaeus's anthem keeps it from dying without the self-shot. Pair it with The Meathook Massacre, Blood Artist, or Zulaport Cutthroat for an actual win.
Infinite mana combos
These produce unbounded mana, which then needs to be spent on something — Walking Ballista, Thoracle plus draw, commander activations, etc. Full breakdown lives at infinite mana combos in commander.
| Combo | Colors | Output |
|---|---|---|
| Devoted Druid + Vizier of Remedies | GW | Tap Druid for G, untap with -1/-1 counter (prevented by Vizier). Infinite green. |
| Basalt Monolith + Power Artifact | U | Tap for 3, untap for 1 (Power Artifact reduces). Infinite colorless. |
| Grim Monolith + Power Artifact | U | Same idea, smaller margin. Infinite colorless. |
| Basalt Monolith + Rings of Brighthearth | any | Copy untap ability. Tap between resolutions for net positive. |
| Isochron Scepter + Dramatic Reversal | U | Imprint Reversal. Tap Scepter for U2, copy Reversal, untap rocks. Needs 3+ nonland mana. |
| Bloom Tender + Freed from the Real | 3+ colors | BT taps for multiple colors. Freed untaps for U. Net positive in 3-color decks. |
| Kinnan + Basalt Monolith | UG | Kinnan adds +1 mana per tap. Tap Basalt for 4, untap for 3. |
| Deadeye Navigator + Peregrine Drake | U | Blink Drake for 1U. Drake untaps 5 lands. Net +3 mana per loop. |
Infinite combat combos
Produces additional combat phases until you swing for lethal commander damage.
| Combo | Colors | Notes |
|---|---|---|
| Aggravated Assault + Sword of Feast and Famine | any 5-land deck | SoFaF triggers on combat damage, untaps lands. Pay 5 to AA for new combat. Loop. |
This one has a sneaky prerequisite — you need to deal combat damage to a player and have the equipment attached. Often listed as 2-card but functionally needs five lands and an unblocked creature. Strong in Voltron-style decks.
Color identity matters more than people think
A combo's color identity includes every mana symbol on both cards. A combo using one card with a B mana symbol and another with a U mana symbol can only be played in a Dimir (UB) or higher color identity commander. Hybrid mana symbols count as both colors. Reminder text doesn't, but rules text does.
This is the most common mistake in self-built decks: someone shoves Thassa's Oracle into a mono-black list because "it's only one blue mana." That's not legal. Consult is fine in mono-black; Oracle isn't. The pair only works in UB or higher.
The combo analyzer catches color identity violations on the first pass. Free, two seconds, paste the list.
Tutoring matters even more
A combo you can't find isn't a combo. The reason cEDH lists run tutors that find specific card types — Worldly Tutor (creature), Mystical Tutor (instant/sorcery), Enlightened Tutor (artifact/enchantment) — is to maximize the chance any given combo piece is reachable from any spot.
Build with this in mind. If both halves of your combo are creatures, you only need creature tutors. If one is an artifact and one is a creature, you need both — or a generic tutor like Demonic or Vampiric. Decks with mixed-type combo pieces and only one tutor type fail to assemble half the time.
What to do once you've picked your combos
Picking combos is the easy part. Recognizing them at the table when half a combo is in your hand and the other half is on the battlefield three turns later — that's where games are won and lost.
The cEDH combo trainer drills you on every combo in your specific decklist via flashcard sessions. Ten minutes a day means you walk into your next pod actually knowing what your 99 can assemble, instead of finding out after you've drawn the wrong tutor target.
For testing, MTG Proxy Cards covers the build phase. Proxy a few different combo shells, drill the combos, run the lists in pods for a month, then commit real money to whichever one you actually want to play.
Frequently asked questions
Find every combo your deck already has
Most decks contain combos their builder didn't notice. Half-pieces that line up by accident, alternate paths through cards already in the 99, and orphan win lines waiting for a partner that's already in the deck.
