Mirror Walk v. Obedience

So if I play Mirror Walk at superior "if this action is blocked, the action ends (with no combat)." and they still block, may they play Obedience to remain untapped?

Obedience reads "Only usable when this reacting vampire is about to enter combat with an acting younger vampire."

"action ends" immediately closes all windows. As soon as the effect of Mirror Walk triggers, no more reactions or action modifiers can be played, so no Obedience.

So that means Lucas Halton could not use his ability? "Once each turn, when Lucas blocks an action, he may burn a blood instead of tapping for the successful block (before combat occurs)."

Obedience = No.
"Only playable when this reacting vampire is about to enter combat with an acting younger vampire."

Mirror Walk triggers before you would ever enter the combat. Since Obedience does not trigger when the block is successful or would be successful, the action is over before Obedience can be played.

IANPB but...
Lucas Halton = Yes
Mirror walk says "If this action IS blocked." Lucas says "when Lucas blocks an action". Both trigger from the same condition, therefore both effects are usable. I would also expect that Cats Guidance would be playable and any other effect asking "is blocked".

I would expect that Mirror Walk would not stop the effects/playability of:
Bloodstorm of Chorazin
Cats Guidance
Darksight
Diabolic Lure
Extortion
Forced Vigilance @[for]
Internal Recursion
Melange
Mental Maze
Minor Irritation
Revelation of Despair
Shattered Mirror
Undying Thirst
Voice of Madness


@Pascal:
How would Mirror Walk and Set's Call work? (One ends the action at the block, the other insists it is successful)

Incorrect.

The acting Methuselah declares that they are blocked (that is, stealth is beaten by intercept). At this point, they have the opportunity to play Change of Target (or similar effects), which goes off:
Which is the same timing as Mirror Walk:
After passing, the blocking Methuselah then has the opportunity to use effects that come in then.

On the specific question of Mirror Walk and Cats Guidance:

No. None of those can be played after the action ends.
No action modifiers or reactions can be played after the action ends.

(Note that "I play MW" is apparently being used as short-hand for "the action ends because of the MW I play". Which might be immediately, since you might be facing +97 intercept and play Mirror Walk to effectively make the action end immediately.)


On the more general point:
[LSJ 20090513] is a discussion between LSJ and Pascal, and gets quite technical.

Essentially, it boils down to the acting Methuselah being able to play "is blocked" effects, then the reacting Methuselah being able to do the same. And this means that - inter alia - Change of Target beats Mental Maze. (Please be careful before cherry-picking from this discussion, because it is quite involved.)

when a block is successful, yes.

Yes.

And Mental Maze's timing is:
Which would seem to be in the same window as:

Moot. The Set's Call can't be played.

Lucas Halton is not a reaction but an effect that triggers off a condition.
As usual, it often seems that my biggest bones of contention with all of LSJs rulings come down to premises and not subsequent logic.
