My opinion is that it's bad to rely on 6 powered cards for your main damage output.
You have too many cards that aren't flexible, so your deck will be easy to play around. Even if you draw Kenny and Cutey together, you might not be able to land either one of them due to their low power. Same with Glorg -- he's not scary vs any 8-power card. Azgroth is a great wall but his damage is shamefully low... And Mawpin is a conditional wall, so she sometimes becomes a liability.
My advice would be to pack your deck with more more threatening cards. Nightmare has a lot of high-damage 4*s, and Karrion is a very scary 5*.
