Found here. I looked up the meaning which suits him well. Granted the description is the normal card but the meaning still applies. Sort of, depending on the canon I guess.
"The Six of Wands depicts a man wearing a victory wreath around his head, riding a white horse through a crowd of cheering people. The white horse represents strength, purity, and the success of an adventure, and the crowd of people demonstrates public recognition for the man’s achievements. The wand held by the rider also has a wreath tied to it, further emphasising success and achievement. He is not afraid to show off to others what he has accomplished in his life so far, and even better, the people around him cheer him along."
