So in other words Valkyrie, you are hardcore for beating one 
I put my chopper and vortexor to the 3rd and 4 places in my new lineup, with an ark I can sacrifice to be sure opponent didn’t stego/charc me (this is rare now I get beat by abusers since they don’t actualize their line-up very often), try to save chopper to a distant site from the front line to avoid stun team, or just put a Mechadino right after the first three to successfully scramble stunners.
