These are the effects:
Question:
If a character has both Super Senses and Mastermind at the same time, can they use both on the same attack? Specifically, I want to know if I can attempt to evade with Super Senses, and then use Mastermind if I fail.

Also, consider this:
Since these are simultaneous effects (triggering off "would be hit"), and it's presumably my opponents turn, would my opponent be the one to choose the order? In that case, I doubt the opponent would ever choose to resolve Super Senses first.

Just to make this relevant, here's a character who has both powers at the same time. It is also the character that made me ask this question:

Yes. Depending of course on what your opponent does based on your second question.

Yes. Mastermind is "may" so you could choose not to use it if your opponent has it resolve first and go for Super Senses if you didn't want to damage the adjacent friendly for some reason.

Yeah, that's what I figured. Thanks!

It's too bad attackers get to choose the order of the defender's own effects now. I get that it's simpler, but it doesn't seem entirely fair. Oh well, at least they remembered to grant the controller control over choice of damage reducer. It would have really sucked if my attacker could force me to use Toughness over Invincible.

Mastermind + Super Senses is a weird corner case/casualty of the 2017 rules.

It used to be that Super Senses triggered on hit and Mastermind triggered on damage being dealt, but now they are in the same timing window.

Dang, I need a pdf of the new rules. I thought Mastermind took effect when the character was targeted for an attack.

A follow-up that came up in a game the other day. A character with Mastermind was single-target Energy Exploded and the one adjacent/lower cost figure has Super Senses and both characters are hit with the attack.

In this case, does the active player (doing the attack) still choose the order of Mastermind and Super Senses?

They would, but if there's an adjacent figure that could normally be masterminded onto, then you can't mastermind the EE unless the main target is hit but the adjacent one is... and if the attacker let the adjacent character roll super senses first to see if it missed, that would be pretty silly of them.

Mastermind can't be used in that case at all.

Wouldn't this work:

1. EE hits both characters. Character A has a higher point value than Character B.
2. Attacker graciously allows defender to resolve Super Senses for Character B first (this would probably never happen, but it is legal).
3. Super Senses succeed, and Character B evades.
4. Character A's Mastermind now resolves.
5. Character B would not be hit by the attack, and can therefore be chosen by Mastermind.
6. Character A uses Mastermind, choosing Character B.
7. Character B becomes hit, and Character A avoids the attack.

Well, yeah, technically.

About this business of the active (attacking) player choosing the order of Super Senses and Mastermind... Where is this precedent coming from?

Mastermind and Super Senses are both optional triggered effects. They both take place during the same step of the attack sequence ("determine hits"), but they're not resolving simultaneously because they don't occur automatically. Neither is in the queue to resolve until the defending/controlling player chooses to use it.

Why could the defending player not choose to activate Super Senses and, if the roll fails, then choose to activate Mastermind because the "would be hit" condition is still there? I can't find anything that says they have to choose to activate optional triggered effects simultaneously.

Because they are both triggered by the same act (would be hit) and thus both would resolve at the same time (if a person chooses to use them).

But, once that choice is made, you don't get to go back and choose to use the other. Technically, you choose what you're going to use and then resolve them (and if you choose to use both, the active player chooses in what order). You don't choose to use Super Senses, resolve it, then choose to use Mastermind. This just isn't how most players play.

But I do love doing it when playing against Skrulls with Shape Change.

They're triggered by the same act, but because they're optional they're not in the queue to resolve unless/until the player chooses to use them. If they were non-optional they'd be in the queue to resolve simultaneously, but they're not. Once the player chooses one, it's resolved immediately. But, there's nothing I can find that says or implies that they have to choose to use them simultaneously.

The rules. The Rule of Active Player was quoted in the opening post.

That's not how triggers work. The triggers themselves are not optional. The optional part is choosing to use the effect.

Both triggers happen simultaneously. The active player (the one making the attack, most likely) decides the order the triggers must be resolved in.

If they choose MM first, then you now must choose whether or not to use the effect from MM. If you choose to use it, then the trigger for SS won't do anything. If you choose not to use it, then you get to roll for SS.

If they choose SS first, then you choose to roll. If you roll and it's successful, you evade the attack, and again, the MM trigger does nothing. If you choose not to roll, or roll and fail, then you get to choose whether to use MM.
