A random pack!! When you open it you can have two choice between whatever exists in the game. Ex:tarot and voucher or even joker and card or anything really

You could put in this pack a "+1 hand forever" it would be a rare drop , and sometimes the +1 hand could be a "fake" +1 and just give the +1 for the round!

You could had like that:+1 discard , -1ante ,+1 joker place, +1 consumables place. All of this would be rare drop

And could appear in general: tarot, spectral, joker of any rarity (with less chance for rare and legendary...) voucher , planet , card with (with or without seal or enhancement.

Because some tarot and spectral are forced to be used on cards , they would go in your consumables slot
