I'm curious to how the resolution of 'Seeker of Knowledge' (as the attacker) and 'Display of Power' (as the defender) would play out. Does my logic make sense here?

Seeker of Knowledge

Phoenix Character. Courtier. Shugenja. Air.

Cost: 2. Military: 0. Political: 2. Glory: 1.

While this character is attacking, the contested ring gains the element. If this character wins the conflict as an attacker, you may choose which of its ring effects to resolve.

Display of Power

Phoenix Event. Spell. Fire.

Cost: 2.

Reaction: After you lose an unopposed conflict – cancel the ring effect of that conflict. Then, you resolve that ring effect as if you had won the conflict as the attacking player. Claim that ring.

1. Attacker wins, defender loses unnoposed (step 3.2.3)

2. Seeker of Knowledge "if" ability initiates (note, this has timing priority over Display of Power because it is a mandatory constant ability, equivalent to the Forced Reaction timing)

3. Attacker chooses to resolve a ring as part of Seeker of Knowledge's ability

4. Reaction window now opens, Defender initiates Display of Power. Display of Power creates a delayed cancel effect (as the cancel takes place in step 3.2.6)

5. Step 3.2.6 occurs, cancel takes place, and the Defender gets to resolve a ring.

How's my timing? Also, Seeker of Knowledge normally grants a second ring resolution for the attacker, right?

To me, when Seeker of Knowledge wins as an attacker, it creates a delayed effect (chooses which ring to resolve) rather than resolving immediately.
ie. When you get to the Resolve Ring Effect step (3.2.6), you resolve the chosen ring effect.

Then, Display of Power is played, and does its stuff.
Seeker of Knowledge gets sad because its choice doesn't matter.

My only (new) question on Seeker, is when is the choice made: during 3.2.3 after winning, or in 3.2.6?

Based on assumptions above, I say that Seeker still only gets one resolution.

Interesting. It seems to me that the template of the Seeker is that it would immediately grant an additional resolution. The rules already grant that a player may resolve any one of the ring's elements:

Quote

Whenever a player resolves a ring effect for a ring that has multiple elements, that player may choose among those elements when the conflict’s ring effect resolves.

So if it wouldn't grant a resolution, this should have just been reminder text.

Also, it follows the 'continuous effect that seeks out a condition' type of card. Once the triggering condition of 'this character wins as an attacker' is met, its effect is applied immediately; which then gives the effect of 'you may choose which ring effect to resolve'.

If Seeker works as you're thinking, it would be a delayed effect at 3.2.6. If it works as how I am proposing, it would resolve at 3.2.3.
