When Gust sends a Sand Soldier back to your hand, does the Sand Soldier just die?

Ruling: The Sand Soldier does not die. It disappears from the game completely and ceases to exist. For any effect that would track it, it did return to hand.

Nuances:

• If a token would leave the board for any reason, it ceases to exist
• The token is not considered to have died, but it does count as having returned to hand for tracking purposes
