I'm assuming you know all the enemies? If not, it's Seria and Lugina who summons Arus and Dilma respectively for round 1. Their attack pattern is very similar to their own trials so it's almost a repeat of their Trials.

After that, Karl comes in and is almost the same as in Trial 1 save for using his 6* BB and SBB instead of Frozen Axe and/or Cursed Blue Slash. He summons 7* Selena and 6* Exvehl as backup. Once you defeat him, he revives and summons 6* Grah. If you survive both of them, you win!
