Forum:Which Cards to Buy?

I'm running an X-Saber Deck, and was wondering which cards would benefit me the most. I was only thinking of getting two of the four synchros on my list next time I'm at the local hobby shop, so which ones would be the best?

P.S. I have all the stereotypical X-Saber cards including XX-Saber Darksoul, but I don't play with Emmersblades, so keep that in mind.

Which Synchro:

XX-Saber Hyunlei, already own one, this would be my second Naturia Barkion Naturia Beast Mist Wurm
