What happens when you remove a token creature from the game, and then return it under it's owner's control?

Question

1. Player A plays Roar of the Wurm
2. Player B plays Astral Slide
3. Player B recycles a card and returns the Wurm token

What happens then?

Answer 1

Tokens disappear whenever they leave the battlefield. The relevant rules are:

110.5f A token that's phased out, or that's in a zone other than the battlefield, ceases to exist. This is a state-based action; see rule 704. (Note that if a token changes zones, applicable triggered abilities will trigger before the token ceases to exist.)

110.5g A token that has left the battlefield can't move to another zone or come back onto the battlefield. If such a token would change zones, it remains in its current zone instead. It ceases to exist the next time state-based actions are checked; see rule 704.

So the Wurm token would be gone for good in this example.
