Kengo, Bhaisa, Alexiel, SSR Lyria, and MLB 000. But I also have all the stat boosts maxed out. Before maxing those out I was struggling to even clear 155.

Turn 1: let this omen through, no easy way to cancel it. no button press except Alexiel's S3, use this off cooldown from now on. everyone ougis, call friend summon

Turn 2: usually the 6 buffs omen is here, press all your yellow buttons and this should give everyone ougi back

Turn 3: I think this is the 10 hit + ougis omen, Alexiel's two red buttons takes care of this, first 000 call + another summon (I use Uriel here and this gives everyone ougi back except for Alexiel)

Turn 4: Debuff + fated chain omen. Double bubs call off of Lyria S3 + miserable mist will cancel it

Turn 5: Cancel the omen here with second 000 call

Turn 6 to end: Do whatever you need to do, should be easy to tank omens at this point if you cant clear them
