Good news and bad news. Mostly good.
The Halloween Overlord Challenge cards arrived today so I will start shipping them out soon.
They look pretty good. A bit glossier than normal cards but not too much. The bad news is I overcompensated on the bleed of the print so while the physical card is the right size, the artwork of the card is a bit smaller than your normal card. It won't effect deck building at least.
Also, I forgot to make the items level text black, so the number is white =(.
Looks weird but overall everything is playable ^^
