Everyone tired of fighting Seymour yet? Not the hardest encounter and not the easiest encounter; Definitely one of the easier ones though. Ultimate dispel + Total Annihilation was really his only major trick and even that is mostly just a timing thing. That said, I do have decent Final Fantasy X real synergy. I went with the standard 3x physical + Medica + Boostga party that I use for most things. The only major difference between my usual party configuration being that I swapped out a 5* support character in favor of Lightning for the sake of having a second Soul Break damage spammer.

Roaming Warrior: Tyro (Sentinel’s Grimoire)
Notable Soul Breaks: Planet Protector, Blade Beam, Blaze Rush, Sentinel, Princess’ Favor
I have mentioned this before but I really like Armor Strike because it multiplies off of DEF and not ATK. I usually have enough attack gear to equip for two characters, but not three. Armor Strike also works very well with Bastion and Cecil’s Sentinel Soul Break
Ultimate Dispel is cast at two fixed points Seymour’s health bar: About 75% and about 50%. Subsequent casts will occur after a certain number of turns if I recall correctly. One of the medal conditions is to default him before he casts it 3 times. After the second Ultimate Dispel, Mortiorchis will cast Total Annihilation (massive AoE damage) periodically; The first cast being a few turns after Ultimate Dispel. The trick to the fight is to not eat an unmitigated Total Annihilation and to burn him down after the second Dispel.
Phase 1: Use Exhausting Polka and Protectga for mitigation. Slow damage to build up SB bars. Cloud uses Tempo Flurry on Mortiorchis to obtain the slow medal condition, Cecil uses Venom Buster on Seymour to obtain the poison/sap medal condition.
Phase 2: Cast Protectga, Sentinel’s Grimoire, and Medica (if needed) after the first Ultimate Dispel. Recast Exhausting Polka if needed though, since it is effectively an AoE Magic Breakdown, Lenna should be keeping the debuff up in between healing rotations (or at least making a point to cast it before 75%~ 50%~ HP). I also had Pecil cast Sentinel to soak all of his single target damage and to buff his Armor Strike Damage output.
Phase 3: Lenna and someone else will need to be held in reserve when he is getting close to 50% health to cast medica and Sentinel’s Grimoire’s respectively. If you do not get mitigation up in time, it will pretty much be a S/L. A raw Total Annihilation will instagib the squishy party members. After TA: Heal up as needed, pop Planet Protector, burn him down with Blade Beam and Blaze Rush.
The vast majority of his attacks are physical based so I dropped Shellga. Total Annihilation however (if I recall correctly) is NAT typed magical damage. Luckily, Sentinel’s Grimoire was sufficient mitigation, though just barely for certain characters.
