Deck Archetype
Every other archetype accumulates an advantage until it is big enough to win. A combo deck skips that: it finds two or three specific cards and the game simply ends.
Combo: Aims to assemble a specific card combination that ends the game.
A combo deck is built to assemble a particular interaction that wins on the spot: an infinite loop, a single enormous turn, or an alternate win condition that ignores damage entirely. The rest of the deck exists to find those pieces, protect them, and survive long enough to deploy them.
That gives combo an unusual deck structure. It is mostly tutors, card selection, interaction, and mana, with a handful of actual win conditions. The archetype spans a huge power range: a casual deck with one two-card combo as a backup plan and a cEDH deck aiming to win on turn three are both combo decks, and the difference is entirely in how ruthlessly the supporting ninety cards are tuned.
Blue and black are the combo colours because they are the tutoring and protection colours. Black finds any card; blue protects the turn you use it and supplies the alternate win conditions. Green tutors creatures and produces the huge mana that powers loops, red supplies rituals and its own creature-based loops, and white contributes tutors for artifacts and enchantments plus a handful of famous two-card kills.
The cards that define the archetype rather than the ones winning this week. If you are building combo for the first time, these are the effects to understand before anything else.
Ten command zones that support the strategy, spread across the color combinations it lives in. The color identity shown is what each commander lets you play in the other 99.
Combo is the archetype where power level is least visible from the outside, and where a mismatch is felt most sharply. A deck that wins on turn four in a pod expecting turn ten is not a better deck, it is a different game. Be specific in the Rule 0 conversation, saying that you have infinite combos and roughly when they land, and know which bracket your build belongs in.
A combo deck is built to assemble a specific set of cards that wins immediately: an infinite loop, a single game-ending turn, or an alternate win condition. Most of the deck is tutors, card selection, protection, and mana, with only a few cards that actually win.
Yes, they are legal. A loop with a mandatory repeating action and no way to stop results in a draw, so you must be able to end it, but combos themselves are permitted. Whether a given pod wants them is a social question, which is what Rule 0 and the bracket system exist to settle.
Combo is a strategy; cEDH is a format-wide power level in which nearly every deck is a tuned combo deck. Plenty of casual decks include a combo as a backup win condition without being anywhere near cEDH. The difference is how efficiently the other ninety cards support it.
