Not really a “bug”, but there is a deck I like to use that revolves solely around all the spells in my deck being “shadow spells”. Well at one point it gave me a choice of “treasures” to choose from. ALL of them were normal spells, which deactivated my minion that made my entire deck work. Why can you not skip getting treasure? Not getting it is probably worse than getting it, but it just limits certain play styles for no reason. Same goes for choosing cards to add to your deck, you should have the option to not obtain any if you don’t want to… very frustrating.
