If today I was forced at gunpoint to go into ranked games, I'd do it with jungle Udyr. I just come to line, press E-R-E-R and snowball myself and my teammates to victory. No trade-offs, no harass, no lane winning. Farm forest a bit until wards expire, come to line, press two buttons, bam! Kill or assist, kthxbye. Full hp and a red bottle after first clean for instant gank. Met enemy jungler at red? Force him to flash away. Enemy doesn't have cc and wants to get away? Too bad. MS quints, ghost and mobility boots a bit later combined with low cd stun spam just won't allow that. Soo easy after Shyvana who appears to be at low HP after first clear and forced to B, well it doesn't matter anyway since she won't be able to do anything on a gank because enemy just walks away. So does enemy jungler if you happen to meet him. Just when you start winning the fight, he'll just walk away laughing at your useless power.
Anyway, Ice Shyvana skin get. Too bad I won't be able to use her against human opponents until buff at least because I just don't know what to do with her to win a game against same level crowd, and I'm usually being matched with/against much more experienced players than I.
