Some months later, Thanatos and Amon U wouldn't be compatible with each other since Amon's frame changes to C frame
but then again that's gonna be awhile before it comes to the nutaku version

For defensive options you can always go Joan + BP or Sniper shot or VoF (to ensure debuffs hit and if you're gonna bring Lu Bu instead)

So maybe something like

1. Joan/Sniper shot + Thanatos + Amon + Beelzebub + (anyone you want, maybe a damage dealer like Rangda or another buffer like Bastet) + 2 himes of your choice in the backline

or
2. Joan/BP or VoF + Thanatos + Amon + Beelzebub + Lu Bu +2 himes of your choice in the backline

but yeah like I said, you're probably gonna have to reorganize some time later
