ok first off i used it in the tourny none of those cards were really allowed
2nd than it doesnt have earth
3rd PAs are VERY useful vs earth and fire and darkness
the list goes on, however that is a viable option yet one i wouldnt take.
1. I was suggesting a general deck
2. Good points, yours is original, but maybe not as capable
3. You can have more copies of skull shields. The thing is, if you add earth to it, you're more prone to useless draws.
