An assistant for every deck
Ask across all your decks and your collection at once: which is strongest, what to build next, what to buy. It can build a new deck or edit one, saving a version first.
How it works
From a sentence to a sideboard.
01
Pour in a theme
Tell Spellpool a commander, a combo, or just a vibe. It reads the whole Oracle text database — not just card names.
02
Swipe the pool
Get a living pool of suggestions ranked for your build. Keep what fits, toss what doesn't. The pool reshapes as you go.
03
Brew to 100
Watch your curve, color identity, and type balance update live. Export to your deck builder the moment it's legal.
Everything in the pool
Build it, score it, play it, own it.
Deck Score and brackets
Speed, consistency, interaction and resilience on DeckCheck's published scale, the Commander bracket it really plays at, and a written analysis of how it wins.
Combos, found for you
Every combo your list can assemble, from Commander Spellbook, with the pieces, what it makes and how it goes off.
Your collection, imported
Upload a CSV from ManaBox, Moxfield, Deckbox, TCGplayer or Archidekt. It keeps the exact printings you own, prices them, and marks owned cards in every deck.
Playtest with a battlefield
Draw opening hands, mulligan, play lands and spells onto a table, and see the odds of hitting what you need.
Versions
Save a deck before a big change, see what changed since, card by card, and restore it when a swap doesn't work out.
Prices and a buy list
What the deck costs, what you already own, and a list of what's missing, ready to order.
On your phone, too
Spellpool works in your phone's browser. Add it to your home screen and your decks, collection and assistant come with you.
Questions
What is Spellpool?
Spellpool is a Magic: The Gathering deck builder with an AI assistant. You describe the deck you want — a commander, a theme, a combo — and it suggests real cards from their rules text, builds to a legal list, and helps you tune it with scores, combos and playtesting.
Which formats does it support?
Commander (EDH) first, with color identity, singleton and 100-card checks built in. Standard, Pioneer, Modern, Legacy, Pauper and other 60-card formats work too.
Is Spellpool free?
Yes. The free plan holds 5 decks, with 4 AI questions and 1 deck scan a day. Spellpool Pro, with no limits, is coming soon.
How does the Deck Score work?
It rates a deck from 0 to 10 on speed, consistency, interaction and resilience, using DeckCheck's published rubric. Speed comes from simulated opening hands. It also reports the Commander bracket the deck plays at, which can be higher than its Game Changer count suggests.
Can I import my collection?
Yes. Paste a list or upload a CSV export from ManaBox, Moxfield, Deckbox, TCGplayer, Archidekt, Dragon Shield or Delver Lens. Spellpool keeps the exact printings you own and shows which cards in each deck you already have.
Where does the card data come from?
Card text, images and prices come from Scryfall, and combos from Commander Spellbook.
