A new way to find your next card.
Start with a strong foundation
We use the top 1,500 commanders and specific commander pairs in EDHREC’s Past 2 Years ranking, skipping configurations that are not Commander-legal. Cards with an unrounded synergy score of at least +5 percentage points form each commander’s reference set. Every currently legal reference card remains available in its list.
Find functional similarities
We include every tag in Scryfall’s card/Oracle tag catalog and exclude the separate artwork-tag catalog. Direct tags and inherited parent tags are available for both commanders and recommendations. We learn distinctive functions from reference cards and look for other legal cards sharing those functions. Creature types and keywords add context and are labeled separately.
Inherited tags receive 35% of their child’s weight per generation, using the shortest path when a tag has multiple parents. We keep the strongest contribution rather than adding duplicates, with no two-generation cutoff. For example, Arcades contributes “buttstrike” directly and “toughness matters” through inheritance. Common tags are downweighted, and the 24 strongest enriched tags form the scoring profile.
“Extrapolated” means outside our +5-point reference set. It does not mean a card is unpopular or unknown to EDHREC. Where available, a card’s observed EDHREC synergy is shown in its details.
Check whether the function fits
Extrapolated suggestions receive a lower fit score when a recognized land-search ability has no eligible targets, or a narrow creature-type buff has little support among the commander’s reference cards. We account for token makers, changelings, type-changing effects, and independent useful abilities. Cards with a lower score for these reasons show “Deck fit checks” in their details.
These are conservative relevance checks, not additional legality rules or a complete model of your deck. Every legal EDHREC reference remains in the list; prerequisite checks do not lower its fit. Unrecognized conditions and more complex interactions still need your judgment.
Read commander tags as deck signals
When a commander has a direct tag such as “typal-zombie,” “synergy-defender,” or “x cost matters,” we use that tag to look for verifiable traits on candidate cards: creature type, changeling, relevant tokens or payoffs, defender, printed card type, actual color, keyword, or an X in a relevant cost. A match gives an extrapolated card a modest boost. A comparable effect that misses the commander’s requirement can receive a lower score; unrelated utility cards stay neutral. Tags whose meaning we cannot verify from card data do not trigger this extra adjustment.
Follow direct commander interactions
For Torbran, clearly self-attributed damage from a nonred card receives a lower fit because Torbran rewards red sources. Cards with useful independent abilities are preserved. For Magus Lucea Kane, an X in a spell mana cost or activated ability cost is a directly copyable interaction; cards that explicitly make mana for X costs are also recognized. Their score gains are modest and cannot override a separate unmet prerequisite. These exact wording checks supplement the broader typed-tag matching. More complex interactions still need your judgment.
Card details explain recognized interactions alongside matching functional tags. A verified interaction is a reason to consider a card, not a promise that it fits your deck.
Weight your commander’s own tags
The commander tag weight slider runs from 1× to 10×, starting at 3×. Each commander contributes its functional tags at that many times the average evidence weight of one legal EDHREC reference card. For pairs, both members contribute. Creature types and keywords do not receive this boost. Commanders without card tags add no boost.
Changing this weight rebuilds the functional profile used for scoring. We retain candidates from the top 300 at every slider setting so stronger commander influence can bring different cards into your list. All legal EDHREC reference cards remain available.
Tune the theme match boost
The theme match boost slider runs from 0× to 3× in quarter steps, starting at 1×, the original typed-tag ranking. It scales only the extra positive score earned from a verified typal, synergy, or matters match on an extrapolated card. At 0× that extra match boost is off. Comparable off-theme penalties, direct interaction scores, and EDHREC-supported cards stay fixed. The slider works with commander tag weight and novelty, and its value stays in a shareable URL.
Choose your amount of novelty
Familiar favors strong fits with a small penalty on reference cards. Balanced gives discoveries more room. Adventurous increases that penalty further. Supported cards stay mixed through the list. The underlying fit score and legality do not change when you move the slider.
Use the evidence, then use your judgment
Fit scores measure relative functional similarity, not win rates or probabilities. Matching tags can miss prerequisites, card efficiency, and incompatible strategies. These are recommendations for individual cards, not a validated 100-card deck or a guarantee of bracket suitability.
Fresh data, a focused prototype
Current snapshot: 2026-09-19. 1,500 commander configurations, including 85 pairs. Card legality and color identity are checked against the snapshot, with additional commander and basic-land-type rules. Changes after that date may not yet be reflected. Up to 300 highest-fit extrapolations are shown at each commander-weight and theme-boost setting.
Card prices and double-faced cards
Prices are USD estimates from TCGplayer supplied by Scryfall, fetched on demand and cached for approximately one hour. Scryfall supplies daily estimates rather than real-time checkout quotes. Prices and product links refer to the same printing; the normal nonfoil price is preferred, with foil or etched-foil prices explicitly labeled when used instead. Shipping is excluded. Missing prices remain marked unavailable. Hover or focus a price link to see when it was fetched.
Click or tap a card with the double-faced indicator to flip it. In recommendation lists, the card name and “Why this card?” open details. Meld cards show the combined meld result when flipped. Split and adventure cards use a single printed face and are not marked as double-faced.
