Spent a bit of time thinking about this, it was pretty difficult to pick only seven players but here my "dream team".
Core:
Thallen - Smart and hes accustomed to different styles and knows how to beat the majority of them
PrimeTime - Hes one of the players I don't like facing in guild spar, hes smart about his movements and does well in teaming others and staying alive
Dante - His GST record speaks for itself really
Clops - No one person has ever taught me more about guild sparring than him, in terms of tactics and spotting great guild sparrers he was light years ahead of everyone else
Ph8 - One of the best clutchers in guild sparring, if he practiced a little more I'd have no doubt that he'd win at least one GST
Subs:
Felix - A very versatile player that you can put into any situation and he'll adapt quickly
Sarah - Because I'm sure people would much rather have her on their team than against them
