Sorry guys, he has a point. It probably doesn't work like that, but there are no restrictions provided on the card. It does not require you to spend the target lock at any particular time or for any particular purpose, only that you are instructed to spend the Target Lock by the attack at hand. "When an attack instructs you to spend a target lock" could mean that the attack instructed you to spend the TL to make the attack at all (and always has up to now), but it also could very well mean that it instructs you to spend the TL to accomplish some other effect.
00supra00 is making a logical point based on a grammatically correct reading of the card. The alternative is more-or-less that it has never done that before, therefore it must never do that. Which would be fine, except that the circumstances that make this possible have never existed before so there is no precedent to follow. Edit: See bottom. I was incorrect, these circumstances have been around for a while.
The card was written long before Norra's ability entered the realm of possibility, and did not use definitive language. If I were you, 00supra00 (and anyone else) I would err on the side of caution and not allow deadeye to operate that way. But in the meantime, it would certainly be something for us to request an FAQ on.
Edit: I realized that there were opportunities for Deadeye to operate this way before, but nobody has ever noticed the possibility. R7 for example, or R4B11. I reiterate that I believe this is incorrect. The explanation for my position is that having an option to spend a TL for a purpose is not the same as being "instructed to spend", the latter implying you have no choice in the matter. Bottom line is that 00supra00 has a point, but I don't believe it is strong enough to carry the argument. IMO deadeye should not be used for Norra's ability or other similar abilities unless and until we receive definitive word otherwise.
