Can I use a Gold gear token to pay for Draven, Vanquisher's ability?

Ruling: You cannot directly use a Gold gear token to pay for Draven, Vanquisher's ability, but you can activate the Gold gear's ability to generate Power, which can then be used to pay for Draven's ability.

Sequence:

• Activate the Gold gear token's ability
• Pay the cost by killing the Gold gear token
• The ability resolves and adds Power to your Rune Pool
• Use the Power from your Rune Pool to pay for Draven, Vanquisher's ability

Nuances:

• The Gold gear token itself is not the payment; it generates the resource (Power) that becomes the payment
• Power costs must be paid with Power from your Rune Pool, not directly with game objects like tokens
