Does Downwell remove Gold tokens from the battlefield?

Ruling: Yes, Downwell affects Gold tokens. Gold is a token gear, and Downwell returns all units and gear to their owners' hands, which includes Gold tokens.

Sequence:

• Downwell resolves and returns all units and gear (including Gold tokens) to their owners' hands
• Gold tokens move to hand as part of the resolution
• Gold tokens immediately cease to exist as a state-based action (tokens cannot exist outside the board)

Nuances:

• While Gold tokens are technically returned to hand by Downwell's effect, they are removed from the game immediately afterward because tokens cannot exist in non-board zones
