111.8. 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.
I am a relatively new MTG player. I learned a lot from this thread (as I do from most threads on this site).
But, one aspect of the OP puzzles me.
Why would the opponent lose any life at all when the Treasure tokens are sacrificed? They are tokens. They never enter the graveyard.
