The only sealed product you can play
Every other sealed Magic product gives you random cards. A Commander precon gives you a deck.
That distinction is larger than it sounds. Open a booster box and you have three hundred and sixty cards and no way to play a game until you build something. Open a precon and you can sit down at a table in ninety seconds.
For anyone entering the format, that is the entire argument, and it holds regardless of how the individual cards compare.
The mana base is what you are buying
Here is the value calculation that people miss, and it is the same insight as with bundles but stronger.
A Commander precon contains 36 to 38 lands, and in a two or three color deck those lands include a meaningful number of nonbasic duals that fix colors.
Now price that separately. A functional three color mana base, bought as singles, routinely costs more than the entire precon. Not a fraction of it, more than all of it.
So the honest framing is: you are buying a mana base, and sixty-odd spells come free. That is why precons are the best value product in Magic and why building the same deck from scratch is usually more expensive rather than less.
The corollary matters for upgrading: do not cut the lands. They are the part you paid for.
What you get, and what it is worth
| Card | Type | Why it is here |
|---|---|---|
| The mana base | 36 to 38 lands | The largest share of the value and the most reusable. Nonbasic duals in particular are expensive as singles and are included here as a matter of course. |
| The reprints | Established staples | Precons are a major reprint vehicle. A single desirable reprint can cover a large fraction of the price, and there are usually several. |
| New exclusive cards | Usually 10 to 15 | Cards printed in the precon before appearing anywhere else. These drive the early demand and are why precons sell out at launch. |
| The commander | One or two legends | Reasonable rather than best in class, by design. Frequently swappable for another legend in the same deck. |
| The accessories | Box, counter, reference | Genuinely useful for a new player, and close to worthless to someone who already has them. |
How to choose one
The question people ask is which precon is strongest. The question that matters is which one you will still want to play in six months.
Choose by colors first. The lands are the most reusable part of the product, and they are only reusable if they are in colors you build in. Buying a precon in colors you will never revisit wastes the most valuable component.
Choose by strategy second. You can replace the commander. You cannot cheaply replace forty cards built around a theme you find boring. If a deck’s plan does not appeal on the box, it will not appeal after ten games.
Prefer two colors for a first deck. Simpler mana, cheaper upgrades, and easier to pilot. Three colors is more powerful and more expensive to improve.
Ignore which is strongest. Precons are balanced against each other. The difference between the best and worst deck in a given release is roughly one turn of speed, which matters far less than whether you enjoy it.
Check for a commander you actually like in the ninety-nine. Precons ship with several legendary creatures. Occasionally the intended commander is not the one you want to lead, and knowing that before buying changes which deck is right.
Where precons genuinely fall short
Being specific, because the gaps are consistent and knowing them is what makes upgrading easy.
Ramp. Around seven pieces where ten is right. The single largest gap.
Card draw. Around six where ten is right. This is why precons run out of gas by turn eight.
Sweepers. Usually one, where two of different types is correct.
Expensive filler. Six to eight cards costing six or more that do something moderate. These exist to make the deck feel exciting to read and are the first cuts.
None of these are mistakes. They follow from a product that must be beatable by other precons, understandable by beginners, exciting to open, and cheap. The design constraints produce these gaps predictably, which is what makes the upgrade path so reliable.
Buying strategy
Buy at release if you want the exclusives. New precon cards are in high demand at launch and frequently sell above retail before being reprinted later.
Buy old ones cheaply if you do not. Precons from previous years are often discounted substantially and are just as playable, because Commander does not rotate and precon power level has not moved dramatically over time.
Buy two if you are teaching someone. Two precons means two people can play immediately. One precon means one person can play and the other watches.
Do not buy four to get all the cards. If you want specific cards from a precon you do not want to play, singles are cheaper. The deck is the product.
Should you upgrade or build from scratch
If you like the deck, upgrade. Ten cheap changes closes most of the gap to a tuned deck, and you keep the mana base you effectively bought the product for.
If you find yourself wanting to change more than twenty-five cards, you are building a new deck with a shared commander. That is fine, and at that point it is worth starting from the slot template rather than from the precon list, because you will make better choices against a blank page than against somebody else’s product.
The precon is still the right purchase in that case, because you keep the lands.
