I've got Shupe's Day Off by crafting and transmuted to premium and put it to any decks. When play it, nothing happened-no trigger events just doomed. what's wrong?

I'm going to take a guess and say Gwent? You might get a faster answer asking in the game's forum:

Blah something find something something wizard.

I'm getting lazy.

Shupe's Day Off only works if you have just ONE of each card in your deck. Otherwise nothing happens.

This is pretty easy as there's a max of two of each bronze card in per deck now. If you pick Shupe in arena, be especially careful as it's easy to mess it up thanks to the card limit removals. Do NOT pick shupe in arena if you have any more than one of any card! Shupe can do that! Or a ranger. Or a soldier.... but he has to have the day off to do it. Trolls these days. First they need days off, next they'll want to be paid in things that aren't rocks!

Thank you for your information. No clear explanation in wiki or somewhereelse, I just lost 800 scrap.
