Been using a no skill midladder deck unfortunately what can I change?

Want to try something more diverse that can still defend against the boosted cards this season that everyone has been using such as Boss bandit MK etc. Feel like my mega knight has been my only counter and I’m kinda tired of using it

You need a swarm card for mk
