i want to mess with him, so how would i go about doing this?
You can't? There aren't any methods available at anywhere close to your level that will do what you want to do, so the only way of doing it is to convince your DM to let you do it, which he seems disinclined to allow.
edit: Better yet, use WIsh to conjure an army of simulacrums and True Polymorph them all into dragons, then true polymorph into a dragon yourself, take that druid.

Because wildshape doesn't let you turn into a dragon. At all.
Find your own truth, choose your enemies carefully, and never deal with a dragon.
"Canon" is what's factual to D&D lore. "Cannon" is what you're going to be shot with if you keep getting the word wrong.
Level 20 wizard, the dragon is just my True Polymorph-ed Simulacrum.

if I edit a message, most of the time it's because of grammar. The rest of the time I'll put "Edit:" at the bottom.
