Let's Play MTG

Your AI deck-building coach.

Meet Jon — he builds a Magic: The Gathering deck with you, one piece at a time, in plain language and at your level. Every card he suggests is a real, legal card. No guesswork, no walls of jargon.

How it works

Whether it's your first deck or your fiftieth, Jon meets you where you are and walks the whole build with you.

01

Tell Jon the basics

Your experience level, your format, and your commander or colours. That's all he needs to start.

02

Build it pillar by pillar

Ramp, card draw, removal, win conditions, mana — Jon takes them one at a time and explains the "why" as you go.

03

Leave with a real list

Every pick is checked against the live card database, so your finished deck is legal, in-colour, and ready to play.

Built to actually help

Coaching, not a card dump. Jon keeps it grounded, clear, and yours.

✔️

Grounded in real cards

Every recommendation is verified against the live Scryfall database. If a card doesn't exist or isn't legal, Jon won't suggest it.

🎚️

Pitched at your level

New to the game or a seasoned brewer — Jon adjusts how much he explains so it never feels over your head or beneath you.

🛠️

Tune-up tools

Once your deck takes shape, one tap to Optimize, Cut 5, Curve Check, Find Synergy, Win Faster, or rebuild On a Budget.

📲

Your decks follow you

Create a player code and your decks travel with you across phone, tablet, and desktop. No email or password required.

Not sure where to start?

Load the ready-made sample Commander deck, poke around the card list, and see how a finished build comes together — then ask Jon to make it yours.
