Advice for my mystic theurge

Been messing around trying to get as many spells/spell slots as possible onto the one character, kinda a jack of all things, going with the trickster path for those extra roguish vibes and the mythic trick wizards spell book, any advice on feats or spells (selection or order) or if different caster classes would work better would be great only made the class on the inevitable excess dlc so not sure how well it’ll do at the main campaign.

Looks good to me. On my Theurge I did Druid Fey speaker and Sylvan Sorcerer and Azata mythic. Only 15th level so far tho.

if you’re going to take the Trickster trick Arcana 1, why not take that first, so you get the better equipment for your whole party way earlier?
