If Warwick's ability triggers when killing a unit, does that unit still deal combat damage or is it taken out of play?

Ruling: Warwick's ability triggers and resolves during the Initial chain when Warwick is made an attacker, killing the targeted unit before the combat damage step occurs. The killed unit does not deal combat damage.

Sequence:

• Warwick is made an attacker
• Warwick's attack trigger goes on the chain during the Initial chain
• The ability resolves, killing the target unit
• Combat damage step occurs (but the killed unit is already gone)

Nuances:

• Bullet Time can be used to move Warwick into a battlefield controlled by an opponent, killing all enemies before combat damage
• Flurry of Blades allows you to deal damage while Warwick's ability is still on the chain
• Warwick's ability cannot trigger across multiple battlefields in the same turn because once combat finishes at one battlefield, all units (including those at other battlefields) heal all damage
