Elliot may be strong, but he fails at strategery. Yes, he is able to think quickly on his feet as has been demonstrated here and later on, but that doesn't mean that he comes up with a good solution. He might have been able to make a deduction on which Nanase was real before she hit, however not only was his deduction incorrect but in the process of doing so completely missed that he probably could have used his Tamashii Gekido to cream all three at once.
As a side note, I like the differnt poof fonts in panel three. I think it's a nice little touch.
