Forum:Help, cyber dragon suggestions

hey, I'm a mediocre duelist, me and my friends have gotten back into the game after finishing school and loving it so much as a kid. the game has stepped up a heap, as much as i think i am caught up i am sure i am not. my friend group are getting rather good, and rather serious, i believe we are all about to start competing in local competition, and i would love not to embarrass myself too much... if i had a chance as well, that could be awesome. suggestions please.

a few little notes, would love more speed i am trying to source some galaxy soldier, but am struggling due to money. and one of my friends has a gravekeepers deck, and i have never been able to defeat it, obviously my deck is graveyard dependent so any help for this specifically would be awesome
