If a hidden Teemo - Strategist is revealed at a challenged battlefield and then killed by Cannon Barrage before his reveal effect resolves, does the effect still resolve and look at the top 5 cards?

Question

Accepted Answer

Ruling: When Teemo dies before his reveal effect resolves, the effect still resolves and reveals the top 5 cards, but it cannot deal any damage because the damage targets an enemy unit "here" (where Teemo is) and Teemo is no longer anywhere.

Sequence:
- Teemo is revealed at the battlefield and his effect triggers
- Cannon Barrage kills Teemo before his effect resolves
- Teemo's effect still resolves and reveals the top 5 cards
- No damage is dealt because Teemo is no longer at a location
