If I have a sprite at a battlefield with hidden Teemo, can I react to the sprite's temporary keyword dying in my beginning phase, and would Teemo then conquer or hold?

Ruling: You can react to Temporary with Teemo, and Teemo would hold since you didn't lose control of the Battlefield.

Sequence:

• Sprite with Temporary dies in your beginning phase
• You can react with hidden Teemo
• Teemo remains hidden (holds) because you maintained control of the Battlefield throughout
