Can you win with purple Draven on a Conquer when you have 6 points?

To determine if you can win the game with Draven, Audacious while at 6 points during a Conquer action, we must look at how points are scored and the restrictions on the final point.

The Short Answer

No, you cannot win the game solely by triggering Draven, Audacious's ability during a single Conquer action if you are at 6 points, unless you have already scored on every other battlefield this turn.

Triggering Draven's ability will bring you to 7 points, but it does not automatically grant the 8th point. To reach 8 points and win, you must satisfy the specific requirements for the final point.

Detailed Breakdown

1. Draven's Ability Timing: According to RiftJudge FAQ #7648, Draven, Audacious's ability triggers during the combat special cleanup, which occurs before the Conquer scoring event. If you are at 6 points and win a combat with Draven, his ability triggers first, bringing your total to 7 points.

2. The Conquer Scoring Event: After Draven's ability resolves and you are at 7 points, the game proceeds to the Conquer scoring event for that battlefield.

3. The Final Point Restriction: According to Rule 448.1.b.2, there is a strict requirement for earning the 8th point (the final point) via a Conquer action:

   "If the player has Scored through a Conquer and has Scored every Battlefield through either method this turn, that player scores the Final Point. If the player has Scored through a Conquer and has not Scored every Battlefield this turn, that player draws a card."

   Because you are at 7 points and attempting to score the final point via a Conquer action, you must have already scored on every battlefield in the game this turn to win. If you have not scored on the other battlefield(s) this turn, you will not gain the 8th point; instead, per Rule 448.1.b.2, you will draw a card.

Summary

• If you have already scored on all other battlefields this turn: You will reach 7 points via Draven's ability, and then successfully score the 8th point via the Conquer action, winning the game.
• If you have NOT scored on all other battlefields this turn: You will reach 7 points via Draven's ability, but the Conquer action will result in drawing a card instead of gaining the 8th point. You will remain at 7 points.

This interpretation is based on Rule 448.1.b.2 and the logic established in RiftJudge FAQ #8506 and #8530.
