Level the playing field

The best games of Commander happen when everyone is on a level playing field. That's what the Rule Zero conversation is for — but it only works when players honestly understand how powerful their decks are.

Brackets are a great starting point, but they only check whether you have specific cards. A deck can stay under the Game Changers limit while packing premium cards in every other slot — and brackets alone won't catch that.

ScryCheck evaluates every card in your deck across five scoring vectors, identifies combos, detects themes, and shows you exactly how every point is calculated.

The result is an honest power level assessment that gives your pod a common language — so nobody shows up with an unfair edge.
