If you reveal hidden Teemo when an enemy attacks, can you use Gust to save him after triggering his search ability?

Ruling: Yes, you can use Gust to save Teemo after revealing him from hidden and triggering his search ability. Teemo won't deal his damage because he is no longer on the battlefield, but he'll be safe in your hand.

Sequence:

• Enemy attacks
• Reveal hidden Teemo (reaction speed)
• Teemo's ability triggers to search top 5 cards
• Use Gust as a reaction to save Teemo
• Teemo returns to hand safely

Nuances:

• You can Gust/Flash Teemo after his trigger resolves, allowing you to get the damage from the trigger and also save him
• Flash can be used to save multiple units (e.g., Teemo and another card) back to your base
• If Teemo is defending (not hidden), you can still Gust him after the chain resolves but before combat damage is applied
• If opponent activates hidden Teemo and you Gust it in chain, the revealing part happens but Teemo won't deal damage since he's no longer there
