Except you're using a shape that is in no way affiliated with the card other than the number 5, which really has no direct affiliation.

That's not a pentagram.

Typically card art is chosen in such a way as to fit the idea of the card, or vice versa. If "Flyfang" had a picture of a finless goldfish, do you think the card art would have been appropriate for a card with such a name, let alone its effect? Probably not.

As far as effects go, however, please correct your stuff according to the [url=http://forum.yugiohcardmaker.net/topic/322020-ocgpsct-thread-writing-your-card-properly/]OGG[/url].
