I've had the pleasure of playing GGG multiple times at this point, and I must say, she is just fun as hell to play with. I completely forget about the drive to win, because conversing with her is just that pleasant, hehe. I also love that she sticks to her guns and works with the Refess, and switches things up now and then. If I recall, last time I played her, it came down to 1 LP each. Never saw it coming. lol. If anyone here has the chance, definately take the opportunity to spend some time with her if you play her, she'll put a smile on your face.
I have yet to play Lupos or Anna, but I would love to. In fact after some expansions, once Lawtia has more of the mechanical cards, I plan to make a "gundam" deck to play against Anna. Cute story behind that one. XD
As for Logress, according to the package I got after the raffle, I'm not sure we've played each other. o_o Neither of us remember. I'd have to see his deck again, but he changes now and then if I recall.
Havent played Csquared yet, and Wildstar and I have a pretty healthy battle record. XD
