What It Is

DeckCheck is an intelligent deck-building platform for Magic: The Gathering Commander, operated by ANTHOS LLC. It is not general-purpose enterprise software, but a highly vertical card-deck-building SaaS product. Its core goal is to help players search Commander decks, build decklists, analyze strategies, evaluate power level, and obtain more objective deck information for Rule 0 discussions.

Core Features and Collaboration Permissions

The product emphasizes that it is “not a souped-up spreadsheet,” but a tool that understands deck strategy. Disclosed features include natural-language Smart Search, card recommendations based on deck-building intent, PowerTune power-level and Bracket optimization, DeckTrim cut suggestions for up to 150 cards, budget and collection filters, Playtester, mana-base optimization, Commander precon browsing, and public deck search. In terms of permissions, decklists, notes, and edits created in the builder are private by default. However, after scanning, submitting, or using features that generate public pages, decks may become public, searchable, indexable, and shareable. The platform does not disclose enterprise collaboration capabilities such as team workspaces, role-based permissions, or approval workflows.

Pricing, Payments, and API

The site states that DeckCheck is “completely free and always will be,” but its terms of service and refund policy also mention first paid purchases, subscriptions, credits, plan changes, and one-time purchases, suggesting that paid benefits may exist or be planned. Specific plans and prices are not disclosed. Payments are processed by Paddle.com as the Merchant of Record, with a 30-day refund guarantee for the first paid purchase. On the developer side, DeckCheck offers a read-only API for public deck data and search, with JSON responses and GET requests. The /deck endpoint can be used without a key, while /deck-search requires an X-Api-Key. The default limit is 10 requests/s, with higher quotas available by request.

Security, Compliance, and Limitations

The terms clearly restrict data scraping, bots, bulk downloads, authentication bypass, API key leaks, model training, and building competing databases. They also state that API access may be limited, suspended, or revoked. However, its security and compliance disclosures are fairly basic: there is no visible information on encryption, audit logs, backup strategy, SOC 2, ISO 27001, GDPR, or similar certifications. The platform also makes clear that once a public deck has been indexed, cached, or referenced by third parties, it cannot guarantee complete removal.

Pros, Cons, and Who It’s For

Its strengths are its strong focus on Commander deck building, recommendation and card-cutting logic that emphasizes strategic relevance, and support for budget and collection constraints. It is well suited to players who want to optimize decks, evaluate power level, and prepare for casual-game discussions, as well as community products that need public deck showcases or lightweight integrations. The downside is that it is not an enterprise-grade SaaS product and lacks information on team permissions, business compliance, and SLAs. The founder background appears to indicate a solo founder, so service and support capacity should be assessed carefully.

Access from China and Alternatives

The main site does not provide information on access from mainland China, supported payment currencies, or localization, so network availability is unknown. Paddle generally supports international payments, but specific China payment methods are not disclosed. Comparable alternatives include Moxfield, Archidekt, EDHREC, TappedOut, and Scryfall.
