Also honestly I suspect trickster may be the suckiest mythic path ever, combat wise, maybe only swarm is worse since you are suddendly alone.
Trickster is OP as fuck, having 11-20 crit range and 5x multiplier on every martial makes the game trivial af, I just rightclicked through everything on core
Good for you, any more detail about your party composition?
I went with my main as full mutation warrior, Wenduag full fighter, Woljif as vivi, Arue full ranger, Nenio full scroll savant, Ember full witch. I didn't feel like building munchkins. I took initiative feats on everyone, and I took that mythic ability, Inspiring Leader I think, on Wenduag, which also adds initiative to everyone. I took persuasion 1 for trickster which gives me free dazzling display on every enemy entering the combat (+ shatter defenses on all martials), arcana trick that give me +1 enchantment bonus on all items, then perception 2 as soon as I could for those crit feats.
Tbh game was pretty easy even before I got the crit feats, just cast phantasmal web/putrefaction/whatever as an opening from Nenio, if bloated stats boss then add some hexes from Ember + ranger bond from Arue and quarry (I had gloves on her that make quarry target take -2AC and sickened without save), and let martials hack everything to pieces. After getting the crit feats I stopped bothering to even open with cast in most fights, because nearly everything melted in one turn from 300+dmg crits on every second hit anyway. My main also had a cleave feat line, and was using reach weapon (Fauchard), so had enough reach to make groups of enemies explode instantly on his own.
