Can anyone tell me what can I do with Wizard tokens?

you can buy stuff at the token shop with them. or sell them.

also. you can use them to vend (2 tokens), buy stuff at blackheart hollow (you'd be lucky to snag something), buy things from the oracle token shop (restocks at midnight), and play everlasting carnival games C: [edit] Wow, how lucky. You stumbled on a Raffle Ticket while making this post! yay~

you also use WT in the pet Zappers.
