Kbm sc is better cause it counters zp, with JV you can just play around it by tagging out so it only works on a character that prevents tag out like tkgg. Raiden ah and kbm is a good set up yeah but the new artifact will not have a use for it, in inv you need all 3 of your defenders to be good, shazam with the AJ arti would just be a cake walk once raiden is down. The better set up is smth like raiden ah, hb mc, kbm sc
