Contextual draft pick evaluation using 8-axis WASPAS scoring across all 31 color archetypes, format-adjusted by empirical win rate so the system steers toward stronger archetypes when commitment is equal. Bayesian-calibrated baseline win rate, archetype-stratified pairwise synergy, curve fit, signal openness, role composition, castability, color commitment, and opportunity cost.

THE DIFFERENCE

What changes

WITHOUT SAVECRAFT
YOU Should I craft Sheoldred for my mono-black deck?
AI Sheoldred, the Apocalypse is a strong card in Standard. At 2BB, she provides card draw and life drain. Definitely worth crafting for mono-black.

Sheoldred rotated out of Standard 6 months ago.

STANDARD — MONO-BLACK WILDCARDS
YOU |

Current format. Real win rates. Your actual wildcards.

WITHOUT SAVECRAFT
YOU Is my Atraxa superfriends deck missing anything?
AI Your Atraxa deck looks solid — lots of options for improvement depending on your playstyle. I'd suggest adding more planeswalkers and counters synergy.

Vague advice. No staple detection. No combo awareness.

COMMANDER — ATRAXA DECK REVIEW
YOU |

EDHREC aggregate data. Specific staples. Real combo lines.

HOW YOU USE IT

Three coaching modes

Same grounded data, three ways to use it. Draft with you live, audit your Constructed build, or dial in your Commander deck.

* DRAFT COACH
YOU P2P1 — Liliana or Elenda? Liliana's the bomb but I'm UW with one black source.
AI Liliana. 63.6% GIH WR vs Elenda's 60.3% — that gap is too large to leave on the table at pick 15. Your archetype confidence is only 0.16, so pivoting to UB or Esper is wide open. The pivot model estimates ~5.4 acquirable black sources over 28 remaining picks. Prioritize black fixing next 3-4 picks.
+ DECK DOCTOR
YOU I have 24 playables in WR. Need to cut 1.
AI Cut Raphael, Tough Turtle. I know, he looks cool — but 52.3% GIH WR and your pool only has 5 red sources for his RR cost. Karsten says you need 8 for on-curve. You're also short on removal (2 pieces vs the 4.6 winning decks average). Everything Pizza does more for this deck.
o COMMANDER ADVISOR
YOU Building Korvold — what combos should I include?
AI Korvold has 12 popular combo lines on EDHREC, 4 with bracket score 4 (fast). Top-ranked: Dockside Extortionist + Temur Sabertooth (infinite mana, 3 pieces, 34% of Korvold decks run it). Food Chain + Squee combos out 2 separate lines. Your RBG identity supports all of them.
