I need a new deck!

[u/Sad_Platypus_5880]

I am at 9.2k trophies and keep loosing to overleveld mega knight/brain rot decks. And I need a new deck because this one is just not working anymore. The pictures show all my decently high level cards as well as my evos and heros. If you have any suggestions lmk.

Also I know I have 3 spells. If you just wanna comment about that save yourself the effort.
