I have had a lot of fun playing my Seong Mi-Na 3 deck but recently at a tourney had a situation come up I had not had before. Durring an attack someone had a card that had both powerfull and an E that would discard all my momentum if it did damage. The turn order went that they played the attack and first thing played their powerfull effect. My first turn I played the E effect from my character that allowed me to discard one momentum and if the attack deals damage I would draw 2 momentum. They then played the attack's E. There was a small debate over if I should be allowed to draw the 2 cards first before the momentum was discarded. The rule that was being cited as saying I do not draw was the Can't vs Can rule. I didn't agree with the interpretation since the effect on Seong Mi-Na did not say I may add cards but that I do add cards, also I had played my effect first. Not wanting to draw the issue out I gave in and just discarded the momentum. I just wanted to know was this ruled correctly? I still don't feel like it was right.

Warderbrad said:

i do not understand where there is a can't in this situation. but floating effects resolve in an order than the active player chooses. so if its his turn, he can decide to play it either way since they are effects triggered by the same event.

I believe that you could draw cards because when the E's are used they set up floating effects that will be resolved if those conditions are met. Then for the attack, the current attacker will decide when certian effects will play out. If he chooses for you to discard momentum, then there would be no momentum left for you to draw.

Before I wade in on this, I apologize, but can I get the exact attack that was used so I can check its card text.

Unfortunately in these situations the exact card text often explains exactly what is to happen, so rather then issue a ruling on a recollection, where often a key word or two has been missed. (Not saying that Warderbrad is inaccurate, but in past in similar situations the recollection has not matched the actual card text)

Note that if you have multiple continuous abilities in play, the active player (the player whose turn it is) resolves all of their continuous abilities in the order of their choosing. Then the other player resolves all of theirs. Then the active player has the first chance to respond to the trigger.

If you and your opponent both have a continuous ability that responds to the trigger of a (or THE) attack (which I think is the situation described) then the active player will have theirs go off first. EG if the attack is a reversal played on your turn you would be able to draw the momentum, but if it's just an attack played on your opponent's turn then your momentum would get discard first.

But of course, do check the actual card's text to make sure.

Stamp for Aslum for explaining the general case very well.
