Mana Base
The Mana Crucible, the lands and ramp that fuel your plan.The crucible where decks live or die. Land count, mana curve, colored-pip math against your sources, and the ramp-draw-interaction trinity, laid bare, ready to tune. The difference between "feels okay" and "hits its plan reliably."
Goldfish

Goldfishing is the Magic player's term for testing a deck by playing it solo, with the opponent doing nothing. You're learning what your deck DOES, not how it fights — exactly what a designer needs before sleeving up against a pod.

Contact & Feedback
Send word, questions, bugs, and ideas all welcome.Got a question, a bug, or an idea? I read every message myself, usually within a day or two. The tool gets better because of these notes. Half the modules on this site started as one-line emails from users.
Arcane Tutor is a deck workshop for Magic: The Gathering. Paste a decklist or a Moxfield URL and you get an AI deck review, a Commander bracket score with a climb path, a goldfish playtester, mana-base diagnostics, auto-detected synergies and combos, live pricing, and a shareable deck card, all built around your list.
What makes it different: every card the AI suggests is verified against Scryfall before it reaches you. Cards that don’t exist get flagged. Cards that break your color identity get flagged. The same scrutiny applies to bracket scoring, recommendations come paired with what to cut from your own list, not generic best-cards advice.
The data is grounded: card lookups from Scryfall, EDHREC’s public JSON for commander stats, and Commander Spellbook for combos.
Built by a Magic newcomer who wished this tool existed during their first deck-building session. Every module here exists because the builder hit that exact problem in their own first weeks, explanations buried in jargon, generic advice that didn’t fit their actual list, AI tools that confidently named cards that don’t exist. Feedback from experienced players is gold; feedback from fellow beginners is just as welcome, if a beginner can’t follow it, that’s a bug.
Thanks for reaching out. I'll read it and get back to you as soon as I can. If it's an urgent bug, a bit more patience, I'm a one-person team here.
