In all seriousness,
Elminster probably does “big Azorius spells” better (but GAAIV is kind of funnier - people go “oh no, stax” and I’m like “where? I just want to cast big sorceries for X=lots”).
Jankier, but possibly some kind of steal deck? Especially if it lets you cast spells for free (or, honestly, cast your own spells for free, that’s as good). I’m thinking Etali, etc. With the exception of
Villainous Wealth this is pretty much all Grixis - stuff like
Chaos Wand,
Fallen Shinobi, I guess stuff like
Zareth San, the Trickster is quite similar. Cheating stuff out might satisfy your desire to do Timmy-esq things, and the randomness means you don’t have to make difficult decisions like what to cast!
I actually have a deck built around
Wild Evocation, but it’s not very good.
In a similar vein, Neera, Jhoira, etc.
