If the opponent uses Imperial Decree, then they push my battlefield that has a purple Draven with a recruit. Does Draven kill the recruit, win the combat, I get a point, then decree kill Draven?

Yes, that is the correct sequence of events. Based on the mechanics of combat and the specific ruling for Imperial Decree interacting with Draven, Audacious (as detailed in FAQ #8630), here is the breakdown of how this resolves:

The Resolution Sequence

1. Combat Damage Step: Combat damage is dealt simultaneously. Assuming the Recruit has less than 6 Might, it takes lethal damage and is marked for death. Draven takes damage (if the Recruit has Might), but survives.
2. Imperial Decree Trigger: Because the Recruit took damage, Imperial Decree's delayed triggered ability ("When any unit takes damage this turn, kill it") triggers. This kill instruction is added to the chain as a Pending Item.
3. Combat Cleanup: Before the Imperial Decree trigger can resolve, the game must complete the Combat Damage Step and perform combat cleanup.
   • The Recruit dies from lethal combat damage.
   • The game determines the winner of the combat. Since only your Draven remains, you are the winner.
4. Draven's Ability: Draven’s ability ("The first time I win a combat each turn, you score 1 point") triggers because you won the combat. This ability resolves immediately, and you score 1 point.
5. Combat Ends: The combat concludes, and the contested status is cleared from the battlefield.
6. Imperial Decree Resolution: Now that combat has fully concluded, the pending Imperial Decree kill trigger resolves from the chain. Draven is killed by this effect.

Important Nuances

• Draven's Death Trigger: Because Draven is killed by the Imperial Decree effect after the combat has already concluded, he is not considered to have died "in combat." Therefore, his death trigger ("When I die in combat, choose an opponent. They score 1 point") does not fire, and your opponent does not score a point.
• Timing: The critical factor is that combat cleanup (including winner determination and win-combat triggers) must complete before the delayed effect from the chain (Imperial Decree) can resolve.

This sequence is consistent with the official ruling in FAQ #8630, which confirms that Draven scores his point and avoids his death penalty when killed by a delayed effect like Imperial Decree after the combat has ended.
