Export the user's MTG Arena (MTGA) collection straight from the running game into their MTG workspace as collection/MTGA-export-<date>.csv, then sync it. Use this skill when the user wants to export, dump, capture, back up, or refresh their MTG Arena collection / owned cards, or asks "what do I own in Arena", or wants their collection available to the deckbuilding skills (mtg-std-build / mtg-std-upgrade prefer cards you already own). It is a one-shot: it reads the owned-card list out of the live MTGA process memory (no anchor cards, no manual steps), names the cards from the local Scryfall database built by the mtg-db skill (never downloading its own card data), and writes a Moxfield-format CSV into the collection folder. The export is then pushed by invoking the mtg-sync skill afterwards (as the normal user — never from inside the export process). Works on Windows (via pymem) and macOS (via Mach APIs; needs sudo). Requires MTG Arena installed and running.
Generate a comprehensive, publish-ready **primer** for an existing 100-card Magic: The Gathering Commander (EDH) deck — a deep "how this deck works and how to pilot it" guide, plus a role-tagged Moxfield import. Use this skill whenever the user wants to explain, document, or write up a Commander deck rather than build, upgrade, or merely rate one: "generate a primer", "write a primer for my deck", "create a deck guide", "explain how my deck works / how do I win with it", "how do I pilot this", "tag my deck by role", "make a Moxfield primer", or "document my <commander> deck". The user gives a deck either by **slug** (a deck already in the workspace, `.mtg/decks/edh/<slug>/import.txt`) or by **pasting a list inline**. The skill reads every card's Oracle text from the local Scryfall database, infers the deck's win conditions and theme, classifies every card into role + theme tags (mana dork, sac outlet, fatty, draw, drain, recursion, removal, finisher, land, …), explains each card in one tight line in the conte
Build a complete, balanced 100-card Magic the Gathering Commander (EDH) deck around a chosen commander. Use this skill whenever the user wants to build, brew, design, or upgrade a Commander/EDH deck, names a legendary creature and asks "build a deck around X", asks for a decklist for a commander, wants help picking cards that synergize with a commander, or wants a Commander deck within a budget or at a specific power bracket. Triggers on phrases like "build me a commander deck", "EDH deck for [commander]", "brew around [legendary creature]", "100-card singleton deck", "help me build my Atraxa deck", or any request that pairs a commander name with deckbuilding. The skill grounds the build in comparable proven decklists (EDHREC average/top/theme/budget pages, optionally top Archidekt/Moxfield lists), assembles a solid reference deck for the target bracket ignoring budget first, then budgets down by role-preserving swaps — prices everything via Scryfall (Cardmarket EUR), reports the deck's ACTUAL (strictly deter
Improve an existing 100-card Magic the Gathering Commander (EDH) deck that the user pastes in. Use this skill whenever the user already has a Commander/EDH decklist and wants to upgrade, tune, optimize, fix, or "make it better" — rather than build a new deck from scratch. Triggers on phrases like "upgrade my commander deck", "improve this EDH deck", "here's my decklist, what should I change", "tune my Atraxa list", "what are the best upgrades for my deck", "help me cut/add cards", or any request that pastes or references an existing 100-card list and asks for improvements. The user pastes their current list inline. The skill diagnoses the deck against a proven methodology and comparable proven decklists (land count, card advantage, ramp, interaction, curve, win conditions, inclusion rates), determines the deck's actual power bracket, then recommends the highest-impact role-preserving swaps within a budget — and because this is an upgrade, the budget is usually much smaller than building a deck from scratch. P
Build a 60-card Standard-format deck for MTG Arena (MTGA), centerpiece-first, tuned against the current ladder meta, and costed in Arena wildcards by rarity. Use whenever the user wants to build, brew, or netdeck a Standard deck for Arena, names a card and asks to build a Standard deck around it, wants a deck for the BO1 ladder or BO3 with a sideboard, asks what to craft for a budget number of wildcards, or wants a deck that beats the current Standard meta. Triggers on phrases like "build me a Standard deck", "MTGA deck for [card]", "brew around [card] in Standard", "budget Arena Standard deck", "what should I craft", or any request pairing Standard/Arena with deckbuilding. Every card is labeled with its rarity and the build respects a wildcard budget tier (1-5). Verifies legality and rarity via Scryfall, and starts from the live competitive metagame and real, current decklists pulled from mtgtop8.com — building meta-relevant, cohesive decks by adapting proven tournament lists to the user's collection and wil
Improve an existing 60-card Standard deck for MTG Arena (MTGA) that the user pastes in. Use this skill whenever the user already has a Standard/Arena decklist and wants to upgrade, tune, optimize, or tech it against the current ladder meta — rather than build a new deck from scratch. Triggers on phrases like "upgrade my Standard deck", "improve this Arena deck", "here's my list, what should I swap", "tune my mono-red for the meta", "what cards should I craft to improve this", or any request that pastes or references an existing 60-card Arena list and asks for improvements. The user pastes their current list inline. The skill diagnoses the deck (curve, mana base, consistency, meta matchups), then recommends the highest-impact swaps — built from cards the user already owns first (via their Arena collection export), and costed in Arena wildcards against a budget tier that, because this is an upgrade, is usually much lower than building from scratch. Verifies legality and rarity via Scryfall, and reads the curren
Analyze and star-rate an existing 100-card Magic the Gathering Commander (EDH) deck that the user pastes in, judged against a target power bracket. Use this skill whenever the user wants their Commander deck rated, scored, graded, reviewed, or assessed — "how good is my deck", "rate my EDH deck", "give my deck a score out of 5", "how does this deck stack up at Bracket 3", "analyze my commander deck", "is this deck any good", "what bracket is my deck", or any request to evaluate a Commander list rather than build or upgrade one. The user pastes their current decklist inline and names (or is asked for) a target bracket (1–5). The skill measures the deck's hard stats (land count, mana curve, ramp/draw/interaction density, EDHREC-rank staple signal, Game Changer count, color-identity legality, price) via the local Scryfall database, reads every card's Oracle text to score synergy density, then awards an overall ★ rating (with a per-dimension scorecard) for how well the deck performs *at its bracket* — covering pe
Collaboratively find the right Magic the Gathering cards for a player by brainstorming with them and researching card text deeply. Use this skill whenever the user wants help finding cards rather than building a whole deck — when they want to pick a commander, fill a specific gap in a deck, add a category (more card advantage, ramp, removal, a finisher, protection), find synergy pieces for a theme or combo, or solve a problem their deck has ("my deck can't close games", "I keep running out of cards", "I die to board wipes", "what's the best removal in these colors"). Triggers on phrases like "help me find cards for…", "what commander should I play", "I need more card draw in my deck", "find me cards that synergize with X", "what should I add to fix Y", "best cards for this strategy", "recommend cards that do Z", or any open-ended card-discovery or deck-problem-solving request that is NOT a full build/upgrade. The skill starts by pinning down the *purpose*, gathers tailored context by brainstorming, then resea
