How Flatman decks play in EDH
Flatman is a mono-green commander costing 3G, and its legendary creature - mutant hero line shapes the whole deck around it. Its ability is narrow enough that the deck is usually built to protect it and repeat the effect, rather than to go wide. The cards below are the ones Flatman decks actually play most often, grouped by the job they do.

Start with FlatmanFlatman deck questions
What colours can I use in a Flatman deck?
Flatman has a mono-green colour identity, so every card in the deck must be green or colourless. That includes mana symbols in rules text, not just casting cost.
What are the best cards for Flatman?
The cards played most often in Flatman decks include Ghalta the Unstoppable, Key to the Side-Door, Warg Tactics. The full list of staples above is grouped by the job each card does, so you can see the deck's skeleton rather than just a pile of names.
How much does a Flatman deck cost?
The 20 most-played cards shown above come to roughly $22.90 at current market prices. A complete 100-card build costs more, and Grimoire can generate a budget version instead if you set a price ceiling.
Can I build a Flatman deck from cards I already own?
Yes. Import your collection into Grimoire and choose "my cards" when you build. The generator will only use cards you actually own, and the Missing Cards page shows what you would need to buy to finish any list.
