MTG Deck Building Basics: Build Your First Magic Deck

Your first deck is going to be a little messy. That’s normal. MTG deck building basics are mostly about cutting the chaos down to one clear plan, then giving your deck enough lands and cheap plays to actually do the plan.

If you’re brand new, you’ll hear a lot of advice that sounds like wizard math. Mana curve. Card advantage. Removal. “Why are you running 67 cards?” Don’t worry. You can build something fun and functional today, even if you only own a small stack of cards and a stubborn belief in big dragons.

Step 1: Pick a format first (deck rules change a lot)

Before you choose colors or cool creatures, decide what you’re building for. Different formats have different deck sizes and card limits. And yes, people absolutely show up with the wrong deck size. It happens.

Here’s the quick-and-clean version:

Format	Typical deck size	Copies allowed	What it feels like
60-card Constructed (kitchen table, Standard, Modern, etc.)	60 minimum	Up to 4 copies (most cards)	More consistent, faster, more “do my thing every game”
Commander (EDH)	Exactly 100	Singleton (mostly 1 copy)	Social, splashy, lots of variety
Limited (Draft/Sealed)	40 minimum	Whatever you opened	Scrappy builds, “make it work” energy

If you’re learning at home with a friend, a Starter Kit or other ready-to-play 60-card decks are a clean start. If you’re joining a casual group night, Commander is common, and a Commander precon will get you into games immediately.

MTG deck building basics start with one simple win plan

A beginner deck usually fails for one reason: it’s trying to do five things and does none of them. Your fix is simple. Pick one main plan and build around it.

Here are four beginner-friendly “deck plans” you’ll see everywhere:

• Aggro: play cheap creatures, attack early, end the game before your opponent stabilizes
• Midrange: solid creatures and answers, you win by being consistently better on turns 3–7
• Control: remove threats, counter key spells, win later with one strong finisher
• Combo: assemble a specific interaction that wins fast (cool, but not the easiest starting point)

If you’re not sure what you like, start with this question:
Do i want to win by attacking, or by controlling the game until i win?
Most new players have more fun attacking first, then learning control later.

The mana base: land count, colors, and why games go sideways

Let’s talk about the thing that makes new decks feel “broken” when they’re not: mana.

Two classic beginner problems:

1. Mana screw: you don’t draw enough lands and can’t cast your spells
2. Mana flood: you draw too many lands and have nothing to do

You can’t eliminate luck, but you can make your deck way more stable with a good land count.

Easy starting land counts

• 60-card decks: start at 24 lands
  • If your deck is super low to the ground (lots of 1–2 mana cards), you can try 22–23 later.
  • If your deck is full of 5–7 mana spells, you may need 25–26.
• Commander (100 cards): start at 37–38 lands
  • Commander decks also run ramp, so you’re not relying on lands alone.

Keep your colors simple

For your first deck, one or two colors is ideal. Three colors is doable, but it’s where mana gets tricky fast, and you’ll lose games to your own deck more than your opponent.

A simple rule that saves a lot of frustration:
If a spell has two of the same colored mana in its cost (like {U}{U}), don’t cram it into a deck that’s “kind of” that color. Make it a real part of the deck or skip it.

Build a mana curve you can actually play

Mana curve is just a fancy way of saying:
What can i do on turns 1, 2, 3, and 4?

A deck full of expensive cards looks awesome in a binder and plays like a sad slideshow. Your early turns matter because they stop you from falling behind.

A beginner-friendly curve idea for 60-card creature decks

You don’t need to follow this perfectly, but it’s a great target:

• Turn 1: a few plays (cheap creature, cheap interaction)
• Turn 2: a lot of plays (this is where you want consistency)
• Turn 3: strong creatures or value cards
• Turn 4: your “big turn” cards
• 5+ mana: only a small number of finishers

If your hand regularly does nothing until turn 4, the deck will feel slow even if the cards are powerful.

The “deck skeleton”: threats, removal, and card draw

Most functional decks are built from the same parts. The mix changes based on your strategy, but the categories stay the same.

In plain terms, you need:

• Threats: ways to win (usually creatures, sometimes planeswalkers or big spells)
• Removal and interaction: ways to stop the opponent’s threats
• Card draw or card selection: ways to avoid running out of gas
• Support cards: ramp, buffs, synergy pieces, utility

Here are two simple starting templates.

60-card beginner template (combat-focused)

• 24 lands
• 20–26 creatures
• 8–12 removal or interaction spells
• 4–8 card draw / card selection / synergy cards

If you’re playing aggressive, your removal might be cheap burn or “fight” spells. If you’re more controlling, your removal will be heavier and you’ll run more draw.

Commander beginner template (precon-friendly)

Commander is bigger and slower, so you want a balanced toolkit:

• 37–38 lands
• Around 10 ramp pieces (mana rocks, land ramp)
• Around 10 card draw pieces
• Around 10 interaction pieces (spot removal, counterspells, etc.)
• 2–3 board wipes
• The rest is your theme, your commander synergy, and your finishers

These numbers are not a law. They’re a starting point that keeps your deck from bricking.

Play a few games, then tune like a normal person

This is where deck building stops being theory and starts getting good.

Play 3–5 games and write down two quick notes after each:

1. What card sat dead in my hand?
2. What did i wish i had drawn instead?

Then make small swaps. One-for-one changes. Don’t rebuild the whole thing every time you lose. Losing is how you learn what your deck is missing.

If you’re building a 60-card deck for match play, your sideboard is where you put “situational” answers. Your main deck should handle the average game. The sideboard handles the specific problem decks you keep running into.

Precon decks: the easiest way to learn deck building fast

If you’re a total noob, precon decks are basically training wheels that still let you go fast.

A precon (preconstructed deck) is a ready-to-play deck built and packaged as a product. You open the box, shuffle, and play. No homework required.

There are a few common types:

• Starter Kits / Arena Starter Kits: two 60-card decks meant for learning with a friend
• Challenger Decks: competitive-leaning 60-card decks designed to be playable right away
• Commander precons: 100-card Commander decks built around a theme and legendary commander

Why precons are so useful for learning:

• They show you what a functional mana base looks like.
• They teach curve without explaining curve.
• They come with interaction, not just creatures.
• They give you a clear theme, so you can feel what synergy looks like.

How to upgrade a precon without getting overwhelmed

Keep it simple. Your first upgrades should make the deck smoother, not “fancier.”

Good first upgrade targets:

• Fix the mana: better lands, more consistent color access
• Add cheap card draw: so you stop topdecking on turn 6
• Upgrade removal: swap clunky answers for cheaper, cleaner ones
• Cut the off-theme cards: precons sometimes include “extra subthemes” that dilute the main plan

And here’s the sneaky part: doing this teaches MTG deck building basics without making you stare at a blank page and 3,000 possible cards.

Common beginner mistakes (and how to dodge them)

You’ll still make some of these. Everyone does. But it helps to know what’s coming.

• Not enough lands. Your deck feels random because it is random.
• Too many colors too soon. Two colors first. You can be greedy later.
• All big spells, no early plays. If you can’t affect the board early, you’re always behind.
• No card draw. You dump your hand, then you’re done.
• Not enough interaction. You can’t just “race” everything, especially in Commander.
• Playing more than 60 cards “because i couldn’t cut anything.” You can cut it. Your deck gets better when you do.
• No clear win condition. Cool cards are not a plan.

Final thoughts

If you remember one thing, make it this: MTG deck building basics are about consistency and focus. Pick a format, pick one plan, run enough lands, and build a curve that lets you play Magic before the game is already out of reach.

And if you want the fastest path from “total noob” to “i upgraded this myself,” start with a precon. You’ll be playing real games immediately, and you’ll learn what to change because you’ll feel it when something’s missing.
