The agent assembled a comprehensive overview of TCG Stacked by combining fragments from multiple successful page fetches and prior knowledge, but had to work around a fragmented information architecture. The site lacks dedicated pricing and features pages (returned 404s), forcing the agent to piece together the value proposition and pricing details from metadata, article pages, and educated guesses about likely URLs. Despite these gaps, the agent delivered a clear explanation of what TCG Stacked does, who it serves, and how it differs from alternatives—though some details about Pro tier features and the full scope of supported games remain incomplete.

• ›Core product information (deck builder, collection tracker, card search, proxy creation) came from page metadata and title tags ([1], [6], [10], [12], [14], [15], [17], [21]), not from richly structured body content. The agent had to infer features from page titles and meta descriptions rather than reading detailed documentation.
• ›Pricing information ($40/year Pro tier, Pro features like dark mode and unlimited decks) was not discoverable through standard navigation—there is no /pricing page. The agent reconstructed pricing by combining web search snippets and prior knowledge, not from the site itself. This is a major discovery-layer friction point: the site does not publish pricing in an agent-accessible location.
• ›The site's information architecture is scattered: /pricing, /about, /features, /faq, and /help all return 404s. Instead, information is embedded in game-specific sections (/mtg, /pokemon, /yugioh) and article pages (/articles/deck-builder, /articles/mobile-app-launch). The agent had to guess URLs and rely on web search to navigate.
• ›The full list of supported games (MTG, Pokémon, Disney Lorcana, One Piece, Star Wars Unlimited, Digimon, Yu-Gi-Oh, Cardfight!! Vanguard, Riftbound) was not consolidated on any one page; the agent discovered them by guessing game-specific URL patterns and web searches, then assembled them.
• ›Mobile app details and card scanning features emerged from search result snippets ([20]) and inferred from app store listings, not from web pages. The site does not clearly document app features in a central location.
• ›Comparisons to alternatives (Moxfield, Scryfall, TappedOut) came entirely from external sources (web search results [16]) and prior knowledge. The site itself does not position itself against competitors or highlight differentiators.
• ›The agent cited multiple URLs as sources ([1], [6], [10], [12], [14], [15], [17], [21], [20]) but most served as confirmation rather than primary information sources. Prior knowledge and web search filled critical gaps, indicating the site is not self-contained.
