Why bring heart breakers into a no heart dungeon?
Yeah, don't do that. lol I need to re-read my posts before I actually toss them up without thinking. Only do this if you wanna lose. Huge brain freeze there. Your spike damage leader of choice with Echidna on 10 turn CD and then fill in subs as needed. I can't really speak to Kirin or Horus's party setup here but, I think I'd Echidna, Parvati (8 turn CD on mine now) and my 2 highest attack stat subs of Water and Dark.
