CURATOR COMMENT-You need to provide a link to the picture source in question (i.e. - provide a link to the PAGE of where the art is found from hawanja's gallery in deviantart - please don't post a direct image link)
I'm not quite sure of the ability - momentum somewhat makes sense, but why does it always generate a photon and a skeleton upon entering the field? Is there some sort of back story or concept behind why the Flying Worm does this? (The similarities to the 'Wyrm' card in-game are only aesthetic and theoretical).
If you want, provide an explanation for your ability if you can in the 'Notes' section of the second table of your original post.
