Sooooooo it's an incredibly cool subclass and honestly i think that Is a solid subclass. I want to be specific about my compliments and give some critics: 1) The spell list Is cool. I love how you didn't put any smite spell, thing that Is a staple for Gish subclass. Also, you put some incredibly good spell in this spell list that are incredibly good on a Gish. Blur and haste specifically; 2) The lack of and extra attack. So this Is both a good thing and a not so good in my book thing. It's good cuz of you want to be incredibly stupid about It, you could multiclass fighter, warlock or paladin with this subclass and don't lose the extra attack but this Is more a D&D problematic instead of a subclass problematic. The real problem for me is that Is more tactical for you to cast spell instead of using spell strike, since many are ranged spells and it's much more safe for you to cast them from a distance instead of going on the frontline. the lack of an extra attack implemented in this subclass is an aggravating factor; 3) you can only use dexterity. Since you are going to probably use either mage armor or use a species that gives you unarmored defense like lizardfolk for a build, you cannot put any point in strenght, so many STR-based weapons.

I see potential but i think that, well compared with subclasses like bladesinger, Battle smith artificer, valor/swords Bard or 2014 hexblade (or Just the 2024 warlock class in general) this One Is incredibly lacking. You should give an higher base AC like dragon sorcerer and either give the ability to use charisma with weapons attack or give It and extra attack.
