When tokens are killed (recruits, sprites, etc), are they sent to trash pile?

Ruling: Tokens do go to the trash pile when killed, but then they immediately cease to exist.

Nuances:

• This matters for cards like Wraith of Echoes and Viktor, Leader, which will trigger when unit tokens hit the trash
• Viktor, Leader triggers for unit tokens as long as they aren't recruits
• Tokens aren't cards, which is relevant for some game effects
