Quick Answer
To build a Commander deck, start with 100 singleton cards led by your chosen commander and stay within its color identity. Balance the deck with 36-38 lands, 8-12 ramp, 8-12 card draw, 8-10 removal, 2-4 board wipes, 2-4 win conditions, and 25-30 synergy cards that support your commander’s plan.
Deck Ratios at a Glance
Your 100 cards break into predictable slots. These ranges work for most Commander decks. Adjust based on your commander and strategy.
| Role | Typical Count | Notes |
|---|---|---|
| Lands | 36-38 | Lower if your curve is low and ramp is heavy. |
| Ramp | 8-12 | More in green; artifact ramp helps non-green decks. |
| Card Draw | 8-12 | Repeatable draw beats one-shot cantrips. |
| Removal | 8-10 | Split between spot removal and board wipes. |
| Board Wipes | 2-4 | More in slower pods; fewer in aggro shells. |
| Win Conditions | 2-4 | Clear closers, not just good cards. |
| Synergy / Flex | 25-30 | Theme, payoffs, protection, and recursion. |
How We Chose These Ratios
These ranges reflect common Commander deckbuilding conventions at casual-to-mid-power tables, checked through goldfishing and against the growing set of decks built with Spellweave. Your exact mix shifts with your commander, your archetype, and your playgroup’s pod speed.

The 7-Step Commander Deck Building Process
Use this sequence for any commander. Skip any step and you risk a shaky deck; follow it and you always end with a playable list.
- 1
Choose your commander
Pick a commander whose ability points toward a clear strategy. Usually a legendary creature; some planeswalkers and special cards qualify too. Color identity, cost, and a repeatable effect matter more than raw power.
- 2
Pick your win condition
Decide how you actually win: combat damage, a combo loop, a value engine that snowballs into a win, or an alternate win condition. Your whole deck will point at this.
- 3
Set your mana base
Start with 37 lands. Add dual lands in your color identity. If your curve averages over 3.5 or you have fewer than 10 ramp spells, add another 1-2 lands.
- 4
Lock in ramp, draw, and removal
Add 8-12 ramp, 8-12 card draw, and 8-10 removal pieces. These are the engine that keeps you alive and relevant.
- 5
Add your synergy package
Fill 25-30 slots with cards that specifically enable or reward your commander’s plan. This is where the deck’s identity lives.
- 6
Check your curve and interaction
Aim for a mana curve peaking at 2-4 mana value. Make sure you have 2-4 board wipes and enough instant-speed answers.
- 7
Goldfish and refine
Draw 5-10 opening hands. Cut cards that are consistently stuck or redundant. A playtested deck beats an over-optimized theory deck.

What Is Commander?
Commander, also called EDH (Elder Dragon Highlander), is one of the most popular casual formats in Magic: The Gathering. It is played with 100-card decks led by a legendary creature called a commander, usually in pods of four, but also works well with 2 to 6 players at the table.
Key Rules
- •Decks have 100 cards in singleton: one copy of each card, except basic lands and cards whose own rules text allows additional copies (like , which says "A deck can have up to nine cards named Nazgûl". The author runs all nine in a Sauron-led Nazgûl tribal deck).
- •Each deck is led by a commander, usually a legendary creature. Some legendary planeswalkers and certain other cards can be commanders if they explicitly say so. Partner, Friends Forever, and Doctor’s Companion allow pairing a second commander; "Choose a Background" lets that commander have a Background enchantment as its second commander.
- •Your commander starts in the command zone, not in your library. You can cast it from there any time you could normally cast it, following standard timing rules.
- •Each time you cast your commander from the command zone after the first, it costs an additional {2} for each previous time you cast it from the command zone this game. This is known as the commander tax.
- •Players start at 40 life, rather than the standard 20.
- •Commander damage rule: if a single commander deals 21 or more combat damage to a player over the course of the game, that player is eliminated.
Color Identity
Your deck can only contain cards whose color identity fits within your commander’s color identity. A card’s color identity is determined by any mana symbols in its mana cost, any mana symbols in its rules text, any color indicator, and any color-defining abilities (e.g., "is all colors"). Reminder text is ignored. For double-faced cards, modal double-faced cards, split cards, and Adventure cards, every face or half counts toward color identity.
Example: Kenrith, the Returned King
costs {4}{W} to cast, but its five activated abilities use all five colors of mana: {R}, {G}, {W}, {U}, and {B}. This gives Kenrith a five-color identity, meaning your deck can include cards of any color.
Basic lands must also match your commander’s color identity. A mono-red commander deck cannot include Plains, Islands, Swamps, or Forests. It can only run Mountains and Wastes (for colorless mana).
Cards with no colored mana symbols, no color indicator, and no color-defining abilities are considered colorless. These cards fit into any Commander deck, including mono-colored ones.
Deck Structure: The Foundation
A well-built Commander deck needs balance across several roles. Every card in your deck should serve a clear purpose. Here is a recommended starting distribution for your 100 cards.
Lands
36-38 cards37 is the most common starting point. Include a mix of basic lands, dual lands, and utility lands that match your commander’s color identity. Consistent mana is the foundation of every good deck. Mana base construction and mana curve go deeper.
Ramp
8-12 cardsRamp means extra mana. Rocks (, ), land searches (, ), and mana creatures (, ) push your plan 1-2 turns ahead. In green, prefer land searches; in non-green decks, mana rocks are the best option.
Card Draw
8-12 cardsWithout replacement, your deck stops affecting the game around turn 6. Prefer recurring sources (, , ) to one-shot card-draw effects.
Removal
8-10 cardsSplit your removal between single-target answers and board wipes.
Strategy Cards
25-30 cardsThese are the cards that advance your deck’s specific game plan. In a tribal deck, these are your key creatures and tribal payoffs. In a spellslinger deck, these are your instants, sorceries, and spell-matters permanents. See the role-by-role breakdown.
Win Conditions
2-4 cardsEvery deck needs reliable ways to close out the game. Without dedicated win conditions, games can stall indefinitely. These might be combos, overwhelming board states, or individual cards that end the game when they resolve.
The Rule of Eight
A common community heuristic, sometimes called the Rule of Eight or 8x8, suggests about 8 cards for each key role. It is not an official rule, but it is a useful starting scaffold when you are building a fresh list.
Example 8x8 Categories
8 categories x 8 cards = 64 nonland cards. Plus 35 lands and your commander totals 100. If you prefer 36 lands, trim one category to 7 cards so 63 + 36 + 1 = 100.
This is a starting framework, not a rigid rule. Many successful decks deviate from it significantly. Some categories may need more cards, others fewer. Adjust based on your commander’s abilities and your overall strategy. The value of the Rule of Eight is that it forces you to think about deck balance before you start adding cards.

Singleton Challenges
With only one copy of each card in a 100-card deck, consistency is much harder than in a 60-card format where you can run four copies of your best cards. You cannot rely on drawing any specific card in a given game.
The best way to mitigate this is to include redundant effects. If your deck needs artifact removal, don’t just run one card that does it. Run three or four different cards that all serve that purpose. This way, even though each card is unique, the effect you need is more likely to show up.
Tutors solve this problem at the cost of raising the perceived power of the deck. and are powerful precisely because they let you find the exact card you need.
Card draw is the most important category in Commander deckbuilding. The more cards you see, the more likely you are to find the answers and threats you need. This is why most experienced players recommend running at least 10 dedicated card draw effects.
Building Around Your Commander
Your commander is the most important card in your deck because it is always available from the command zone. Unlike every other card, you are guaranteed access to it every game. This means you should build your deck to maximize its abilities.
If your commander draws cards, you can afford to run fewer dedicated card draw spells and use those slots for more synergy pieces. If your commander provides ramp, you might cut a few ramp spells in favor of payoffs that benefit from the extra mana. Browse common EDH archetypes to see which plan fits your commander.
Planning for Commander Tax
Each time you cast your commander from the command zone, the cost goes up by {2} for every previous cast from there this game. On the third cast it is {4} more; on the fourth it is {6} more. Plan mana rocks and cost reducers to keep pace.
Where Does Your Commander Go?
When your commander is sent to the graveyard or exile, it goes there first (so "dies" triggers still fire), and then you may move it to the command zone as a state-based action. When your commander would go to your hand or library, you may send it to the command zone instead, and it never enters those zones. Either way, commander tax increases based on how many times the commander has been cast from the command zone, not on how many times it has returned there.
The best Commander decks are synergistic with their commander but not completely dependent on it. If your entire strategy collapses the moment your commander is removed, the deck is too fragile. Build redundancy into your game plan so you can still operate when your commander is unavailable.

Common Commander Deck Building Mistakes
New players trip on the same handful of pitfalls. Knowing them upfront saves you three or four deck revisions.
Running too few lands
Most decks need 36-38. Under 34 and you will mana-screw constantly. A cheap curve and extra ramp only lets you drop by 2-3, not 5.
Not enough card draw
Without 8-12 draw pieces, you run out of gas around turn 6 and stop affecting the game. Repeatable draw engines are non-negotiable.
No clear win condition
A pile of good cards is not a deck. Pick one or two paths to victory and make sure your 98 other cards get you there.
Curve too high
Casual decks live or die on turns 3-5. If most of your deck costs 5+, your commander and board never stabilize. Aim for an average mana value near 3.
Forgetting instant-speed interaction
Sorcery-speed only answers mean you lose to the first combo player at the table. Run 3-5 instants that handle creatures, artifacts, or enchantments.
Over-relying on the commander
If every plan needs the commander on the battlefield, targeted removal wrecks you. Build a deck that functions without it too.
