But... But... I was the one who voted for that option first! .
It doesn't matter though. All that matters is that we finally DID get the correct definition.
Actually you talked about a different thing.
You talked about
quantum usage. If a deck uses only gravity quantum (and free cards) it's a mono-gravity, etc
This other idea originally by Lanidrak doesn't talk about quantum usage, it talks only about
card costs. The difference is that with this definition you can take
any mark you like and it doesn't effect the category of your deck.
This is how it should be and that's what makes this definition better than others. It's bulletproof as there are no decks that can "break" this definition. At least none that I can think of.
