Good to know

  • Whetstone can't see your collection, so wildcard costs assume you own none of the cards.
  • Alchemy (rebalanced "A-") cards are not supported; Scryfall no longer lists them separately.
  • The power tier is a rule of thumb from the deck's structure. With meta lists it is much better at judging card quality.
  • Your decks never leave your browser. Share links carry the list after the #, which browsers don't send to servers.
