When Teemo Scout is revealed from hidden, can you respond to its on-play ability with Gust before the on-play resolves?

Ruling: Yes, you can respond to Teemo Scout's on-play ability with Gust. Gust will resolve first, bouncing Teemo back to hand before the on-play ability resolves.

Sequence:

• Teemo Scout is revealed from hidden
• Teemo's on-play ability triggers and goes on the chain
• You can respond by playing Gust, which goes on the chain above the on-play ability
• Gust resolves first, returning Teemo to hand
• Teemo's on-play ability then resolves
