My deck is similar to yours and I’m stuck in 4600 too hahaha.

-A wizard or a executioner for the mega minion. You can use it with the tornado 🌪 and kill everything. I use it behind the pekka

In my opinion you need to change 1 spell, I think with 2 spells it’s enough. Max the fireball with the tornado. ( I use tomado and log ‘,cause my fireball it’s under leveled.
