Can Teemo be played hidden on a battlefield location where a Spirit unit is, and then revealed on a later turn, or does Teemo disappear due to the Spirit's Temporary ability?

Ruling: You can play Teemo hidden on a battlefield location with a Spirit unit. Temporary is a triggered ability that uses the chain and can be responded to, so you can reveal and play Teemo in response to the Temporary trigger.

Sequence:

• Play Teemo hidden on the battlefield location where Spirit is
• When you want to reveal Teemo, the Temporary trigger goes on the chain
• Respond to the Temporary trigger by revealing and playing Teemo
• Teemo resolves before the Temporary trigger removes the Spirit
