Does anyone know how to get tokens? I have no clue.

The above link is the Festival Task Log. Completing daily tasks rewards you with Frost Tokens. Most are fairly easy, like nurturing 100 pets, or defeating 50 enemies in the festival zone. Most of the tasks link to where they need to be completed. If you meant Snow Wars Tokens, you are given enough free battle tokens a day (not quite sure when they're topped off or by how much) to get you through the "Complete Snow Wars" tasks. I hope this helps.
