Okay, this card is very vague in how it can be played, I need some opinions.

1. It says once per round, but the attack phase is called attack Phase... so can you only play it once per phase, or is it just once per ship?

2. The card says Once per round, before you roll 1 or more defense dice, you may guess aloud a number of evade results. If you roll that many evade results (before modifying dice), add 1 evade result. To me it reads that you must guess a number over 0, because if you don't roll any evades, then this card cannot activate. If you roll that many evade results (before modifying dice), add 1 evade result The bold section is where things get confusing, because it specifically says if you roll that many Evades, so if you rolled 0 Evades, you really never completed the card specifications... Maybe I'm reading too much into it, but it seems a little vague.

I think you're over thinking it bud. You can guess zero and if you do not roll an evade, you get 1. It could be a blank or a focus, neither are an evade so the ability would trigger. To clerify the other part, you may only use this card once per attack round, NOT every time the ship with C3PO is attacked. Hope that helps!

1. A round is planning phase, activation phase, attack phase and endphase. So once only per round.

2.If you guess 0 evades and roll a blank or an eye you have rolled zero evades and gain 1 evade from C3PO because you have guessed the number of evade you rolled correctly. You can roll zero evades so that is a legitimate result to guess.

Yeah. FFG has made it clear in every ruling that they consider 0 a number.

You may choose 0 evade results with C-3P0, even if you are rolling 0 agility dice.

You may spend a focus to modify 0 eye-ball results (most notably with Garven)

You may spend a Target Lock to re-roll 0 dice.

You may declare an attack even if you have 0 attack dice to roll.

et c. et c. et c.

You may choose 0 evade results with C-3P0, even if you are rolling 0 agility dice.

This is actually not quite true as C-3PO specifically requires that you be about to roll 1 or more agility dice, but you can still pick 0 as the number you are about to roll.

I can't think of any functional differences right now between "once per round" and "once per phase" for this ability, but if there's ever a situation where you would roll defense dice outside of the attack phase, then it would matter...

Corran Horn can attack in the End Phase, I believe. So the time is near.

Right you are. I was thinking he was "at the end of the attack phase" but after checking it's actually "at the start of the end phase." In that case, the "once per round" means that you cannot use C-3PO both for an attack in the attack phase and Corran's attack in the end phase. You could use it on either of those, but not both.

Okay, this card is very vague in how it can be played

I don't really see how this is at all vague. Once per attack phase, guess a number of evades (eg "one") if you roll that number of evade results before you modify your dice, then add an extra evade result... That's it.

Except that you can have more than one attack phase per round... so you have to pick the one you want to use it on.

ONCE per attack phase. Also known as "Against a Single attack of your choosing". Still not vague.

There is only ever one combat phase per round (although, as has been pointed out, it will soon be possible to have an attack occur outside of the combat phase, but that isn't really relevant to the card.)

There can be more than one attack during a combat phase, requiering you to make a decision on when to use threepio, but that just means the card is situationally useful, not that there is any ambiguity about how it works.

Well no. The card can be used once per round.

Oops, bad wording on my part. Of course only one attack PHASE per round (for now), but more than one ATTACK. That's what I get for posting late after a loooooong day...
