How it works
The flow is simple: build a list, read what Cardmere noticed, then decide what you want to change.
1
Describe the deck
Use normal language. Mention the game, format, budget, power, theme, or cards you want to build around.
2
Review the list
Open Deck Quality, Deck Info, Doctor, and Balance tools to see what looks strong or risky.

Keep improving
Simulate games, browse cards, save versions, compare with your collection, and keep tuning.
