BackstockTCG › Magic deck builder
A Magic: The Gathering deck builder that knows what you own
Build Commander, Modern, Standard, Pioneer, Pauper and more. Bring decks in from Moxfield, Archidekt, ManaBox, MTG Arena or MTGO, see which cards are already in your collection, and find the rest at stores near you.
Everything you expect from a deck builder
Search every card
Search by name or with Scryfall syntax, and pick the exact printing and finish.
Boards and categories
Commander, companion, main deck, sideboard and maybeboard; group by type, your own categories, mana value or colour, as a list or pictures.
Stats that matter
Mana curve, colour pips against land sources, card types, deck price, and the cheapest printings to hit a budget.
Format checks
Deck size, copy limits, banned and restricted cards, colour identity, and legal commander pairs.
Commander brackets
An estimate from Game Changers, mass land denial and extra-turn cards, with your own bracket shown on the deck.
Versions
Earlier lists are kept, so you can compare changes and go back.
Connected to your cards and your local store
Own vs. need
Every card shows whether it's in your collection. Copy the missing list or add it to a store's want list.
Find missing cards at stores
See which stores have the cards you're missing in stock, at their price, and ask one to pull them.
Pull lists
Where each card you own is: binder, box or location, ticked off as you pull.
Sample hands
Draw opening hands with the London mulligan, and see the odds of hitting your lands and early plays.
Share and export
A share link anyone can open, decks on your public profile, and export for Moxfield, Archidekt, Arena or MTGO.
Scan cards in
Use the card scanner to add cards straight into a deck, or add a deck's cards to your collection.
Questions
Can I import my decks from Moxfield or Archidekt?
Yes. Paste a list or choose the exported file from Moxfield, Archidekt (with categories), ManaBox, MTG Arena, MTGO, dot.gg, TappedOut, Forge or a CSV. Exact printings, foils, commanders and sideboards come along.
Does it check Commander rules?
Yes: 100 cards, singleton, colour identity, banned cards, and which commanders can be paired (Partner, Partner with, Friends forever, Backgrounds, and the Doctor and companion). It also estimates the deck's Commander bracket from Game Changers, mass land denial and extra turns.
Is the deck builder free?
Yes. Building, importing, exporting, deck checks, stats, sharing and own vs. need are free. Pull lists and sample hands are part of Collector Premium. See pricing.
What about other games?
Magic comes first. Deck building for Pokémon, One Piece, Lorcana and the other games is on the way, one game at a time.
