When can we pre-order the "D&D Reference Cards"?

To kick off the magic, you’ll be able to add new tools to your table in August with D&D Reference Cards, built to keep key information close at hand when the action heats up.

As an Australian, I tend to need to pre-order things if I want to actually get them to arrive anywhere near the real release time.  As such, I'd like to know when we can preorder the D&D Reference Cards that are coming in August.

Also, could we have a bit more of a description of what they actual are, because I'm preordering based on what I think they are, but I'm hoping I'm not wrong.

Based upon the advance publicity for the "Season of Magic", these cards might become available in late summer or early fall 2026. I intend to monitor Amazon during that time for the sale. As far as the content of this card deck, one can only hope for the best.
