What constitutes winning a combat for the purpose of Draven's legend and unit abilities?

Ruling: You win a combat if only your units remain at the battlefield after combat concludes. Combat consists of three steps (Showdown, Damage, Resolution), and winning is determined at the end of Resolution, not just after damage is dealt.

Sequence:

• Combat is staged when units from opposing players are present at the same battlefield
• Combat Showdown begins (includes Initial Chain with When I Attack/When I Defend triggers)
• Once Showdown has begun, you are in Combat
• Damage step occurs (can be skipped if no units remain)
• Resolution step occurs
• At end of Resolution, if only your units remain, you won the combat

Nuances:

• You can win combat without dealing damage (e.g., using Hextech Ray or Rebuke during Showdown to remove opposing units)
• Uncontested conquers are NOT combat (no opposing units present)
• If units are removed before combat actually begins (e.g., Fight or Flight during a move trigger before combat opens), no combat occurs and Draven doesn't trigger
• Once combat has started, removing opposing units by any means counts as winning
• If a combat is staged but unstaged before it begins (units removed during move trigger resolution), no combat occurred
• Ties are calculated after combat damage is dealt, suggesting win/loss is also determined at that point or after
