If you know the CardCast code, you can try https://pretendyoure.xyz/zy/metrics/deck/code.

You can also use CrCast decks. Just click COPY URL, paste into the location bar, and save and use that file.

Decks saved from this page can be used with Cards Against Humanity online clones that support deck importing, such as CLRTD.com and Gianlu.xyz (but not PYX yet).
