I am running the Draven champion, my opp is currently in control of a bf with an Overzealous Fan, I use my unit to contest that battlefield and my opp trigger the Overzealous Fan, killing it to move my unit back to base. Does that consider as me winning the combat because the Overzealous Fan is being killed first or is there no outcome? Provide the full resolution breakdown.

To determine the result of this encounter, we must follow the sequence defined in the Showdown Flow and the Rules FAQ.

The Verdict

This is "No Result." You do not win the combat because you never established control of the battlefield by having units remain there while your opponent had none. By moving your unit to the base, the battlefield ends up with no units remaining for either player.

According to Rule 461.3.d, if neither player has units present during the "Determine Combat Result" step, the result is "No Result," and the battlefield becomes uncontrolled (Rule 461.5.b).

Resolution Breakdown

1. Initial Chain (Showdown Begins): You move your unit to the battlefield controlled by your opponent's Overzealous Fan. The battlefield becomes Contested.
2. Triggered Ability: Because the Overzealous Fan is at the contested battlefield, it gains the "Defender" designation. Its ability—"When I defend, you may kill me to move an attacking unit to its base"—triggers and is placed on the chain.
3. Chain Resolution:
   • Your opponent resolves the trigger. They pay the cost (killing Overzealous Fan).
   • The effect resolves: Your attacking unit is moved back to your base.
4. Showdown Ends: The chain is now empty, and both players pass focus. The showdown closes.
5. Combat Cleanup: Since no units are currently present at the battlefield, the game performs a cleanup.
6. Determine Combat Result: The game checks the battlefield for units.
   • Because your unit was moved to the base and the Overzealous Fan was killed, zero units remain at the battlefield.
   • Per Rule 461.3.d, the result is "No Result."
   • Per Rule 461.5.b, the battlefield becomes Uncontrolled.

Because no one established control, no Conquer occurs, and no combat-win-related triggers (such as those from Draven legends) will fire.

Note: This interpretation is based on the provided showdown flow and rules for combat resolution. No official FAQ exists for this specific scenario, but it follows directly from Rule 461.3.d and Rule 461.5.b regarding combat results when no units remain.
