Um i use valk logbait w/ Guards(dont judge me) and ive tried classic challenges and the most ive gotten is 6 wins. I've lvlved it up with book of cards so here are my lvls
What is your deck right now? Sadly, being underleveled in midladder usually means that you can't push much anymore :( But you can't play some classic challenges, or some grand challenges if you feel very confident. Get your deck leveled up and then you'll be able to push out of midladder. :)
