If Teemo dies in the chain before his ability resolves, does he still get his effect?

Ruling: If Teemo dies before his ability resolves, he cannot deal damage because his ability specifies 'here' and he is no longer at the battlefield (he's in the trash). However, you still reveal 5 cards.

Sequence:

• Teemo's ability goes on the chain
• Teemo is killed by another effect in the chain
• Teemo's ability resolves but cannot find a valid target 'here' for the damage
• The reveal 5 portion still occurs

Nuances:

• The keyword 'here' is critical - it requires Teemo to still be at the battlefield location when the ability resolves
• Only the damage portion fails; the reveal portion of the ability still happens
