Im level 150 and i beat it with a team of 4 omni and 1 friend (also omni). heres my squad and why i picked them. hopefully you have some of those units that helps.

Fina lead. She reduces the bb gauge cost, so my mitigator can get that defense buff and damage reducing bb up faster

Rain. He is my mititgator (other units do this just fine, rain is just the one i have) and he gives with sp 50% damage reduction for 2 turns off of bb. This was my most important part. You have to get that damage reduction by the next turn after you start, or you get destroyed. This can also be done with fujin tonic.

Zero. He boosts my spark damage (again other units do this just as well), and makes spark damage heal and boost bb gauge. This took out the need for a healer cause my spark damage healed so much. And the spark to bb gauge also helped,

Finally Mariela. She boosts the od fill rate, for getting od much faster. I also have her for damage boosting bb bar. That really helps when a single unit is the boss, and sparks dont help as much for boosting my bb gauge.

My friend i brought was adriesta. for the elemental damage negation, and her ubb skill. Her ubb gives a 25000 (yes, thats 3 zeros) thunder barrier. this was extremely important for the final boss of oracle knights order. After the boss reaches a certain hp, he releases an attack that wipes ALL buffs. Defense boost, damage reduction, bb attack, everything. However, barriers cannot be buff wiped. so this protected my units on the final boss.

Hopefully this helps and wasnt too wordy. Let me know what units you try.
