What Is Commander?
Commander (also called EDH — Elder Dragon Highlander) is the most popular Magic: The Gathering format. You choose a legendary creature as your Commander, then build a 100-card singleton deck using only cards that match your Commander's color identity. Each player starts at 40 life, and the format is designed for 4-player multiplayer games.
Commander is where MTG's most social, creative, and political gameplay happens. Games go long. Interactions matter. Your Commander's identity shapes every card choice you make.
Commander Deck Building Rules
100 Cards Exactly
Your deck must contain exactly 100 cards including your Commander. One card in the Command Zone, 99 in the library.
Singleton (1 of Each)
Only one copy of any card is allowed — except Basic Lands. This creates maximally varied games and forces creative choices.
Color Identity
Every non-land card must fit within your Commander's color identity — defined by all mana symbols in the card's mana cost AND rules text.
Legendary Commander
Your Commander must be a legendary creature (or a card that says it can be a Commander). It starts in the Command Zone and can be cast repeatedly.
Commander Damage
21 points of combat damage from a single Commander kills a player — regardless of life total. Track it per Commander.
40 Starting Life
All players begin with 40 life instead of the standard 20. Games run longer and big-mana plays are rewarded.
Color Identity Explained
Color identity is the most important constraint in Commander deck building. It's determined by all colored mana symbols that appear on a card — including the mana cost, rules text, and reminder text (but not flavor text).
| Commander Color Identity | What You Can Include | Example Commanders |
|---|---|---|
| ⚪ White (Mono) | White cards + colorless + basic plains | Heliod, Sun-Crowned |
| 🔵🔴 Two-color (Izzet) | Blue, Red, colorless cards + basic Islands/Mountains | Niv-Mizzet, Parun |
| ⚫🔴🟢 Three-color (Jund) | Black, Red, Green cards + colorless + basics | Korvold, Fae-Cursed King |
| ⚪🔵⚫🔴🟢 Five-color | Any card in the game | Golos, Tireless Pilgrim |
Commander Mana Curve Targets
Getting the mana curve right is critical in Commander because you need to do meaningful things at every stage of a 40-life multiplayer game. CardForge analyzes your deck's mana curve automatically.
- 1–2 CMC: Mana ramp (Sol Ring, Rampant Growth), cheap interaction, cantrips. Aim for 10–14 cards.
- 3–4 CMC: Your value engines, early threats, synergy pieces. The most contested slot — aim for 20–25 cards.
- 5–6 CMC: Finishers, board wipes, big draw spells. 10–14 cards max.
- 7+ CMC: Format staples only (Ulamog, Expropriate). Keep this under 5 unless your deck specifically ramps here.
- Lands: 36–38 lands is the Commander sweet spot. Include mana rocks to compensate for higher curves.

Commander Format Popularity
Commander is the most played Magic: The Gathering format worldwide. According to Wizards of the Coast, the format has grown explosively — new Commander precon sets now outsell standard booster packs. The singleton format means every game is unique, and the 100-card deck size means there's always room to express your personality through card choices.
Popular Commander archetypes include:
- Voltron — Equip and buff a single creature (usually the Commander) to kill with Commander damage.
- Stax / Prison — Disrupt opponents with resource denial while advancing your own gameplan.
- Combo — Assemble a two- or three-card infinite combo to win in one turn.
- Spellslinger — Cast lots of instants and sorceries for value; Niv-Mizzet Parun is the archetype's poster child.
- Tribal — Fill your deck with creatures sharing a type (Elves, Dragons, Zombies) and leverage tribal synergies.
- Goodstuff — High-power individual cards with no single synergy thread. Works best in 4–5 color decks.
