If Warwick's ability is activated to destroy all damaged units, but Overzealous Fan chains to send Warwick to base before his ability resolves, will the damaged Mountain Drake die?

Ruling: When Overzealous Fan sends Warwick to base before his ability resolves, Mountain Drake will not die because Warwick's ability specifies "here" and he is no longer at that battlefield when his ability resolves.

Sequence:

• Attacker puts "when I attack" triggers on the chain (Warwick's ability)
• Defender puts "when I defend" triggers on the chain (Overzealous Fan)
• Fan resolves first, returning Warwick to base
• Warwick's ability resolves, but "here" now refers to a different location with no enemy units
• Mountain Drake survives and heals damage at end of combat

Nuances:

• The opponent could instead pay 2 for Bullet Time and then attack to kill the Drake and conquer the battlefield
