Any tips

Onslaught seems to be the general R4 option

You have many good options. Who do you enjoy playing the most?
I think this is the most important question that can answer your dilema.

Shang Chi

or storm

Glad to see another R3 Moleman

Do caiw. He's the one I most want to face in your BG deck
