Nice pickup! I know it isn't the strongest card but that Stardust card is one I always like to see and hope to get it at some point.
I combined my Bryan and fed a couple lower cards to it. Fed my Legendary Pro Kane to the first RTG Batista. My RTG lineup from strongest to weakest is now as follows:
RTGP Sting/RTGP Reigns/RTGP BNB/SP Flair
SP Sting (Surfer)/SP Edge/SP DiBiase/RTG Batista
LP Rock/LP Rock/SP Bryan (til he's fully leveled)/LP Hogan
LP Cena/LP Undertaker/LP Show/LP Batista
SP Eve/SP Tamina/LP Brie/LP Natalya
Also working on a LP HHH after I level up Bryan, as I think he is a little higher up than Batista and Show at least. That is, unless I get a pair for Survivor Pros in KOTR.
By the way, I beat the 2 seed in the 2nd round in 2 games, going right into the finals. The #1 seed and the other guy (5, I think) went to three games. Waiting for my finals opponent, so another consecutive finals berth and if not two survivors, I wil get a nice Legendary support to use for feeding.
