when i click on it to use it, it doesn't get selected, and when i save it in the deck builder, i get a connection error message, it's not saying that i'm using too many provisions or anything, so what's the problem?
Ask a Dev is not meant for tech support, so I have moved your post here. As for your problem, does your deck include Treant Mantis: Stalk? Because the card is bugged, at the moment. If not, can you make a screenshot of your deck and post it here?
