The Commander Deck Template
Start with an idea you love (a card, a mechanic, a whole style of play) and build from there. Here's the supporting-cast ratio that turns it into a deck that actually holds up in the games that matter.

The same ratio in two shapes: a one-page sheet to print and fill in as you build, and a phone-sized card to keep open while you shop for cards. Free, no email required.
Start with an idea you like
Every good deck starts with an idea, not a spreadsheet, and the idea doesn't have to be a single card. Sometimes it is: one card is cool enough to build 99 more around it. Just as often it's a mechanic you want to lean into, or a whole style of play. Some players build every deck around combat in some new shape: go-wide, voltron, extra combats. Others chase spellslinger shells stuffed with cheap instants and sorceries, or group hugs where the win condition is almost beside the point. All of those are exactly the right place to start.
The idea just can't be the whole deck. You've played the game where nobody at the table can answer the one threat that matters, and you've played the one that's all removal and no payoff: four players staring at empty boards until someone decks out. Both are the same gap: a great idea with nothing built to support it. The other cards are what let that idea actually happen at the table, ramping you there, drawing you into it, and keeping it alive once it's in motion.
The template
These aren't hard rules. They're a starting ratio to build from, then adjust as your deck's plan comes into focus.
Higher curve decks want closer to 38-39 lands. Fast, low-curve decks can trim to 35 and lean on ramp spells instead. Landfall decks go the other way and run up to 42, where lands aren't just how you cast your spells, they're the payoff, and the extra hits are worth the flooding risk. The categories don't need hard walls either: a lot of good ramp rocks also draw cards, a lot of removal doubles as a win condition.
Example cards for each slot
A few staples worth knowing by name in each category, the kind of cards that show up across dozens of good decklists because they simply do their job well.
Ramp
Ramp gets you ahead of the game's natural mana curve, playing your bombs a turn or two early instead of waiting on lands alone. In a 4-player game, tempo compounds fast, so a few good ramp pieces early can decide who's casting a game-changer first. Most of these ten slots end up being artifacts, and which ones depends on your color count more than anything else. see the full mana rocks guide →
Card draw
Games go long, and the player who runs out of cards first usually runs out of answers first too. Draw engines keep your hand full so you're never just topdecking and hoping.
Removal / interaction
Not every threat can be raced. Removal and interaction are how you buy time, answer the thing that's about to end the game, and stay relevant against plans your deck can't out-value.
Wipes & protection
The smallest category on purpose: a couple of board wipes for when you're behind, and a couple of ways to protect your own board when you're ahead, so one removal spell doesn't undo your whole game plan.
Building to the template: a worked example
Let's put it into practice with Atraxa, Praetors' Voice, a four-color commander built around counters and card advantage.
Commander Spotlight
Atraxa, Praetors' Voice ↗
37 lands leaning on fixing lands since the deck is four colors. Ramp slots favor mana rocks like Arcane Signet over land-fetch, since Atraxa wants counters and card draw more than raw land count. Draw is stacked toward proliferate synergy: cards that grow counters while replacing themselves. Removal stays flexible (Swords, Beast Within) since the deck isn't fast enough to need a hyper-aggressive answer suite. Win cons lean on proliferate payoffs: a handful of planeswalkers and counter-doublers that turn every proliferate trigger into a snowball.
Common mistakes
Too many "win-more" cards. Cards that only matter when you're already winning don't help you get there.
Not enough interaction. A deck with zero removal is a deck that loses to the first real threat it sees.
Curve too top-heavy. A deck full of 6-drops with no early plays just dies before it gets to do anything.
