A clear path from idea to deck

Build in three quick steps.

01

Pick your cards

Search the catalog and add the cards or commander you want to build around.

02

Set constraints

Choose a format, budget, collection, sets, mechanics, and preferred play style.

03

Generate and refine

Compare variants, inspect the curve, pin favorites, and export your final list.

Built for experimentation

More building, less busywork.

Generation runs locally after the compact card library loads, so trying another seed or variant does not require another server round trip.

Seed-first workflow

Start from the cards that inspired the deck instead of a blank list.

Real constraints

Respect format legality, color identity, budget, sets, and your collection.

Useful variants

Compare several approaches without rebuilding your settings every time.

Ready to play

Review mana curves, sideboards, prices, and export-ready lists.
