How to Build a Mana Curve in Commander: The Complete Guide

A smooth mana curve means you have something to do every turn. A bad mana curve means you're either doing nothing for the first three turns or running out of things to cast late game.

What Is a Mana Curve?

Your mana curve is the distribution of mana costs across your non-land cards. In Commander, a good curve usually looks like a bell centered around 3 mana value:

• - 0-1 mana: 8-12 cards (ramp, cheap interaction)
• - 2 mana: 12-16 cards (signets, removal, utility)
• - 3 mana: 12-16 cards (the sweet spot for value cards)
• - 4 mana: 8-12 cards (your commander often sits here)
• - 5 mana: 5-8 cards (powerful effects)
• - 6 mana: 3-5 cards (bombs and finishers)
• - 7+ mana: 2-4 cards (game-enders only)

Average Mana Value (AMV)

Your average mana value should be between 2.5 and 3.5 for most decks. Calculate it by adding up all mana costs and dividing by the number of non-land cards.

• - Under 2.5: Very aggressive or combo-focused. Needs fewer lands.
• - 2.5-3.5: Standard range. 36-38 lands is correct.
• - Over 3.5: Battlecruiser or big mana. Needs more lands and ramp.

The Turn 1-3 Test

Draw 7 cards 10 times and see if you can do something meaningful in the first 3 turns. If you're consistently doing nothing before turn 4, your curve is too heavy.

Good things to do turns 1-3: - Cast a mana rock (Sol Ring, Signets) - Play a creature or enchantment that generates value - Hold up removal or interaction - Ramp with a land-fetching spell

Common Curve Mistakes

• Too many 5+ drops — Exciting cards tend to be expensive. Resist the urge.
• No 1-drops — You should have 8-12 cards that cost 0-1 mana.
• Counting commander in the curve — Your commander's cost is relevant but it's not a card in your 99.
• Ignoring alternate costs — Delve, convoke, and cost-reduction effects change your effective curve.
