Hello I have several cards /items /potions etc in my wizard area. When I start a new game and select bookworm as the hero, I am not getting anyghing at all from my starting deck. I would also like to know what's the difference on the cards if they are highlighted yellow from the ones that are not. I know my profile shows level 22,but I am level 44 on the season

Normally you should get a school book and a frozen book at the start of the game when you use bookworm. The yellow border means that you can use this card on golden grounds. And there are some advanced items that don’t drop unless you crafted/bought them. Which is also the yellow frame.
