At first glance , from someone like me who barely has much knowledge of Raid , id say lv60 scyl will help in dungeons .. her passive and kit is pretty nice and does not require books to be good .

Then Allure and Coldheart are very useful TM champions .. 

I would also focus on gettnig those mentionned to 60 all while maybe showing us the type of gear you have , cuz the issue could be gear wise more than champion wise ..

Id also wait for more than just my advice ... i can barely tell what champions you have because idk half of them >,<

It'd help if you sorted by rarity, but for now, I think I would prioritize Scyl, Valkyrie, UDK, and Ronda. They'll carry you through most dungeons.

I put all of them in my vaults because if I left them in my Champion Info tab that you click to look through them, the photos would be massive. Even the basic tools and controls I'm so dumb with. 

Vault sorts by the same order your main champ list sorts by :)

Oh, well, thats cool. Is there a way you can lock the list? In my main list, I can select rarity but every time I go back to it, it changes back to rank.

Rank will always be default when you go to your champ page. With roster screenshots it's just often easier to view in: panoramic view, screenshots cropped in order of your rank/rarity as sorted automatically.

Is panaramic view something you can get in game settings or do you have to do phone settings?

Click the button in between champion count and the three lines which will give you...

This view. Then you can clip as such. :)
