Take a 3 level dip for INT shillelagh then multiclass to bladesinger. That's my best idea for what to do with it.
It's only fine if the campaign doesn't stop abruptly when your Maverick reaches the 4th level or something.Yeah the subclass really picks up at 9th level. Is that an issue? Eh, sometimes different power curves for subclasses are fine. You're not too far behind on spell slots until then (3rd vs. 5th starts to get noticeable), and if you're playing Maverick you've already accepted that DPR isn't your main metric.
Artificers get a good selection of spells to load into their spell storing item anyway. I don't think there are any 2nd level spells on other class lists that are so earth-shatteringly good to be worth giving up a robo-dog for.
For example, Faerie Fire is already an Artificer spell.
