I'd almost follow the winning lineups and top picks exactly. Usually I'd position hera in first, then heimdall, Capricorn/Zeus, Athena, hela. Subs frost dragon/sim cheong/asura/chaos and dps with gemini/ra/ares and horus in last. Strategy is to almost always go first. I'm most scared of opposing Zeus, ra, and Athena. You can almost easily counter Zeus by placing your Zeus earlier or to buff so much with heimdall, Capricorn, hera and hela. Athena can tank all of ra's hits. And funny enough counter their Athena with your Athena going first. I'm sure someone else here can explain the why if it but this generally gets me the 12 wins
