How to build a 100-card Commander deck
Learning how to build a Commander deck can seem difficult: thousands of cards, only one copy each and exactly 100 slots. The common mistake is adding everything that looks fun and discovering too late that you lack lands, draw or real ways to win.
Build by role instead. First create the framework that lets the deck play; then add cards developing the commander’s personality.
This guide includes a 2026 Commander deck template, memorable proportions and a step-by-step process for any legendary creature.
Commander deckbuilding template
This distribution is not an official rule, but provides a balanced starting point:
| Role | Starting count |
|---|---|
| Commander | 1 |
| Lands | 37 |
| Ramp and mana fixing | 10 |
| Draw and card advantage | 10 |
| Targeted interaction | 10 |
| Board wipes | 3 |
| Protection and recursion | 4 |
| Synergies and win conditions | 25 |
| Total | 100 |
Ratios vary by deck. An aggressive cheap-spell list may use fewer lands; an expensive Dragon deck needs more mana. Start with a complete structure and adjust using game data.
Step 1: choose a commander with a clear plan
Your first deck’s best commander need not be the most powerful. Find a card clearly answering these questions:
- What does it want the deck to do?
- How does it generate advantage?
- Which colours can I use?
- Can it help even when I am behind?
- Can I explain its intended win in one sentence?
Avoid complete dependence on the commander remaining in play. If every card only works with it present, simple removal can stop the entire deck.
Step 2: define how you will win
Before searching for cards, write a sentence:
“This deck wins by…”
Possible answers:
- Attacking with many creatures
- Dealing 21 commander damage
- Creating and boosting tokens
- Draining every opponent’s life
- Reanimating graveyard threats
- Assembling a specific card combination
- Accumulating resources to cast a decisive effect
Step 3: start with 37 lands
“How many lands does a Commander deck run?” has no universal answer, but 37 is a safe first-draft foundation.
Adjust like this:
- 34 to 36 lands: low curve, cheap commander and at least ten efficient ramp pieces
- 36 to 38 lands: most casual and medium-power decks
- 38 to 40 lands: expensive commanders, land strategies or many high-cost spells
Dual lands help, but you do not need an expensive mana base to start. Basics enter untapped, are reliable and preserve your budget.
Step 4: add 10 ramp cards
Ramp means producing more mana than playing one land per turn would generate. It is essential in Commander because there are several opponents and spells tend to be larger.
There are three main families:
- Mana rocks: artifacts producing mana
- Land search: spells putting additional lands into play
- Mana creatures: creatures that tap to produce resources
Step 5: reserve 10 slots for card draw
Commander games can last many turns. If you play your entire hand and then draw only one card per turn, three opponents have time to overtake you.
Draw does not always say “draw a card”. These also generate advantage:
- Creatures replacing the invested card when they enter
- Permanents drawing repeatedly
- Spells recovering several graveyard cards
- Effects exiling cards and allowing you to play them
- Commanders creating resources each turn
Step 6: include answers to different problems
A deck cannot only execute its own plan. An opponent will play a huge creature, a resource-generating artifact or an enchantment stopping your strategy.
Dedicate around ten slots to targeted interaction:
- Creature destruction or exile
- Artifact answers
- Enchantment answers
- Counterspells if playing blue
- Protection for an important piece
- Effects disrupting graveyards
Also add two or three board wipes. They are your emergency button when an opponent has too many creatures or the game gets out of control.
Step 7: protect and recover important cards
The clearer your plan, the easier it is for opponents to identify destruction targets. Include three or four protection or recursion cards:
- Grant indestructible or hexproof
- Return a card to hand
- Recover permanents from the graveyard
- Protect several creatures at once
- Sacrifice a piece for value before losing it
Step 8: complete the deck with synergies
Now comes the fun part. Remaining slots develop the main theme:
- Creatures of the chosen type
- Cards enabling the commander’s abilities
- Rewards for repeating the central action
- Ways to finish the game
- Favourite cards that work within the plan
For a specific piece, use Deck Lab’s Magic singles search. Filter by name, set, rarity, language and condition.
How to build a good mana curve
The mana curve shows how many cards you have at each cost. A common mistake is filling the deck with spectacular five-, six- and seven-mana spells.
As guidance:
- Include many two- and three-mana actions
- Limit five-mana-plus cards to those genuinely changing the game
- Count actual cost, not just printed cost: a seven-mana spell usually costing three should be evaluated differently
- If the commander costs six or more, increase ramp and protection
Colour identity and legal cards
The 99 cards must respect the commander’s colour identity, including mana symbols in its cost and rules text.
A white-blue commander can use white, blue, white-blue and colourless cards, but none with black, red or green symbols in their identity.
You must also follow the current banned list. Before buying an expensive piece, check Commander legality and the official format rules.
The five-hand test
Before finishing the deck, shuffle and draw five different opening hands. Check each:
- Do I have two to four lands?
- Can I produce the required colours?
- Do I have a play in the first three turns?
- Is there ramp, draw or interaction?
- Does the hand function without drawing one exact card?
How to upgrade after playing
Make small changes of three to five cards. After each game, record:
- Cards you could never cast
- Mana colours you lacked
- Times you ran out of cards
- Threats you could not answer
- Cards that looked powerful but did not help the plan
- How you won or why you could not finish
Mistakes to avoid when building Commander
Adding too many themes
Dragons, tokens, graveyards and instants can each be good strategies, but mixing all of them reduces cooperation between cards.
Copying a list without understanding it
An online list may include combos, budget decisions or cards adapted to a particular table. Use it as a reference, not an automatic answer.
Forgetting the total budget
Set the budget before choosing cards. Reserve some for mana and seek functional alternatives when a piece is not essential.
Building only for when ahead
Include cards useful from behind: wipes, recovery, draw and flexible answers.
Not discussing power level
A legal deck can still be a poor fit for a table. Explain infinite combos, Game Changers or particularly fast win conditions.
Build it yourself or ask for help?
Building is part of the fun, but finding cards, balancing roles and checking prices takes time.
If you know the legendary creature but not how to turn it into a coherent list, request a custom Commander deck. Specify commander, strategy and budget and receive a tailored proposal.

Commander deckbuilding FAQs
How many lands should a Commander deck have?
Start with 36 to 38 lands. Then adjust for curve, commander cost and ramp count.
How many ramp cards do I need?
8 to 12 usually works for most casual decks. Ten is a memorable starting point.
How many cards can repeat?
Normally one copy per name, except basics and cards explicitly allowing more.
What proportion should go to the strategy?
After lands, ramp, draw, interaction and protection, usually 20–30 slots remain. There is no fixed number: some cards serve several roles.
Can I build a budget Commander deck?
Yes. Use a simple mana base, avoid nonessential expensive cards and prioritise functional redundancy. Consistency does not depend only on price.
Must I follow this template exactly?
No. It is an initial framework to avoid gaps. Games reveal which areas need more space and which can shrink.
Start with the framework, not the 100 cards
The best answer to how to build a Commander deck is a process rather than a fixed list: choose a plan, reserve essential roles, complete synergies and adjust after playing.
Use the template as a first draft. Once the deck produces mana consistently, keeps cards in hand and answers the table, you have a base worth customising.
