Search commanders, build mana bases, suggest precon upgrades, find cheaper replacements, repair missing roles and review bracket changes. Results include estimated prices, tradeoffs, warnings and optional TCGplayer affiliate shopping links. Public tools work without an account. Optional account sync restores private multi-deck plans, collections and priorities across devices and connected MCP clients. Suggestions do not certify deck power or legality, and links do not place orders.",
