Use Landfiller to build a 37-land mana base for Tatyova, Benthic Druid under $100, bracket 3. Show the quantities, estimated cost, reasoning, color coverage, and every warning.
The assistant can call search_commanders to find an exact name, then build_mana_base. Builds support 30–42 lands, budgets from $20 to $10,000, brackets 1–5, optional acceleration, and excluded cards.
Review the result before shopping
Prices are estimates. Color-coverage warnings describe tradeoffs and should remain visible. TCGplayer list imports use card names; the selected printing and final cart price may differ. Shopping links are affiliate links and do not place an order. MCP builds are previews and are not saved as public builds.
