i used 6* royal fencer & light healer leads with 7*snake spirit(immortal), Lycan of the moon, Echidna & 8*blue dragon as striker
sits at about 16667 hp with 50% reduced green damage, round delay, poison, ignore defense, heal and big hitter i didnt have to use a revive til stage 6
...it just kept double hitting over and over and over...but i did beat it so i guess technically its viable team
lol 7 revives total btw GL
