first you kill their main that is never full immune, that alone clears 99% of the combos the full immune team can do. At that point you nuke 1 by 1 the single ninjas with high damage mysteries/standards.

immortal teams work if you have total higher hp than the enemy, so that you win in round 10 by having more hp XD.

@for the OP: if you run an heavy cc/debuffs team you are simply facing your antimeta and you simply can't win. This happens for every meta. If you want to win you need to change lineup, main or talents.
