Work with the DM, not against them.

I like the aspect of Wish in being any other spell, but outside of chain simulacrums and whatnot, there’s other good 9th levels to compete with it.

I like the idea (DM being okay with it) of using it for backlash-inducing wishes, like the ones in the spell description. There’s a whole separate set of fun to roll the % to see just how many damage types you’ll get to resist.

I’m also a fan of using Wish to add off list spells to my caster’s spells known.

But again, I’d suggest not trying to surprise your DM with this and run your thoughts by them before you get there.
