How many cards should I cut from a precon?

A good starting point is ten to fifteen cards. These are usually the overcosted vanilla creatures, narrow situational spells, and anything that does not support your commander's strategy. Cut first, then fill those slots with ramp, draw, removal, and better lands.

What should I add first when upgrading?

Prioritize the three pillars: ramp (mana rocks and dorks like Sol Ring and Arcane Signet), card draw engines in your colors, and removal including a couple of board wipes. Then fix the mana base. Deck-staple lists for your color identity are the quickest, most budget-friendly way to find these cards.

How many lands should a Commander deck run?

Most decks want about 36 to 38 lands alongside roughly ten ramp pieces, though very low-curve or combo decks can go a little lower. Just as important as the count is the color balance: make sure your sources match the colored mana your spells demand.

How to Upgrade a Commander Precon Deck: A Step-by-Step Framework

A practical framework for upgrading a Commander precon by cutting weak cards and adding ramp, draw, and removal.

Start by Cutting the Weakest Cards

Every Commander precon ships with filler designed to teach new players rather than win games, so the first step is identifying cards to cut. Look for overcosted vanilla creatures, narrow situational spells, and cards that do not advance your commander's plan. A useful test is to ask whether you would be happy drawing the card on turn eight when the game is wide open; if the answer is no, it is a strong cut candidate. Aim to free up ten to fifteen slots before you add anything.

Be honest about cards that look exciting but rarely perform. High-cost bombs with no protection, build-around enchantments that need other pieces, and reactive cards that sit dead in your hand all bloat a deck. Cutting them is not about removing fun; it is about making room for cards that consistently improve your average game. Keep your commander's identity in mind so that every cut and addition pushes the deck toward a clearer, more focused game plan.

Add the Pillars: Ramp, Draw, and Removal

Most precons are short on the three pillars that make Commander decks function: ramp, card draw, and interaction. A healthy 100-card deck typically wants roughly ten pieces of ramp, ten sources of card advantage, and ten pieces of removal, adjusted for your commander and curve. Ramp like Sol Ring, Arcane Signet, and on-color mana rocks or dorks lets you deploy your commander and threats ahead of schedule, which is one of the biggest power jumps you can make for little money.

For card draw, lean on repeatable engines in your colors rather than one-shot effects, and for removal include a mix of spot removal and at least a couple of board wipes so you are not helpless against a developed board. Linking out to widely played deck staples is the fastest way to find the right cards: staple lists for each color identity show the ramp, draw, and removal that experienced players run again and again, and they are usually budget-friendly. Slot these in first, then refine.

Tighten the Mana Base and Curve

Precon mana bases are notoriously inconsistent, often running too few lands of the colors you actually need and too many that enter tapped. Upgrading your lands, adding a few dual lands or fetches within budget, and making sure your color sources match your deck's pip requirements will smooth out your draws more than almost any single spell. Most Commander decks want somewhere around 36 to 38 lands plus your ramp package, though combo and low-curve decks can run fewer.

Finally, look at your overall mana curve. After cutting filler and adding pillars, a deck can drift toward too many expensive cards, which leads to clunky hands. Make sure you have enough early plays to use your mana on turns one through three, and that your top end is reserved for genuine payoffs. A focused curve, a reliable mana base, and the ramp-draw-removal pillars together turn a sloppy precon into a deck that plays smoothly and wins more often.
