Build a Commander Collection That Grows With You
Commander is Magic's most popular format. Here is how to invest in the staples, decide what to share across decks, and turn a preconstructed deck into something powerful.
How Commander Shapes a Collection
Commander, also called EDH, is played with 100-card singleton decks — one legendary creature as your commander and 99 other cards, no more than one copy of each except basic lands. That singleton rule changes how you collect: instead of chasing four-of playsets, you want breadth, a wide pool of one-of cards you can slot into decks. The format is casual and social, built around big multiplayer games, so the collection you build for it leans toward flavorful, splashy, and interactive cards rather than the tightest competitive lists.
Staples Worth Owning
A handful of cards show up in a huge share of Commander decks, and they are the smartest early purchases because they earn their slot everywhere. Sol Ring is the definitive example — a cheap artifact that ramps your mana and goes in almost every deck. Command Tower is a land that taps for any color in your commander's identity, making it an auto-include in multicolor decks. Mana rocks like the signets and Arcane Signet, along with staple removal and card draw, round out the core toolkit. Buying these staples once and knowing their market value keeps you from overpaying, and Tappr's live pricing makes it easy to check before you commit.
Per-Deck Versus Shared Pools
Because every Commander deck is singleton, you face a choice with your staples: buy a copy for each deck, or keep one copy and swap it between decks as you play them. Many collectors keep a shared pool of expensive staples and physically move them from deck to deck, leaving an open slot or a placeholder when a card is on loan to another list. Others buy multiples of the cheapest, most-used cards — like Sol Ring — so no deck is ever missing one. A digital inventory helps here: track which deck a card is currently in so you always know where your staples live.
Upgrading Preconstructed Decks
Preconstructed Commander decks (precons) are the easiest on-ramp — a ready-to-play 100-card deck out of the box, released alongside most sets. They are also a great-value starting point for a collection, since a precon gives you a legal deck plus a pile of reprinted staples at a low per-card cost. From there you upgrade gradually: cut the weakest cards, add better ramp, removal, and cards that support your commander's strategy. Scan the deck into Tappr to see its total value and identify which upgrades give the most improvement per dollar before you buy anything.
Common questions
01 What are the most important Commander staples to buy first?
Start with universal ramp and fixing: Sol Ring and Command Tower go in nearly every deck, followed by mana rocks like Arcane Signet and the signets. These cards appear across almost all Commander decks, so buying them early gives you the most reuse. Check current prices in Tappr before purchasing.
02 Do I need a separate Sol Ring for every deck?
Not necessarily. Sol Ring is cheap enough that many players buy one per deck for convenience, but you can also keep a shared pool of staples and move them between decks as you play. Tracking which deck a card is in with a digital inventory prevents confusion.
03 Why is Commander built around single copies of cards?
Commander is a singleton format: decks are 100 cards with only one copy of each non-basic card, plus a legendary commander. This rewards a broad, varied collection over playsets and is a big reason the format is so beginner-friendly and endlessly replayable.
04 Are preconstructed Commander decks worth buying?
Yes — precons are the best entry point. You get a fully legal deck plus reprinted staples at a low per-card cost, then upgrade over time. Scan a precon into Tappr to see its total value and spot the highest-impact upgrades before spending more.
