Actually in my opinion Contrary can kind of compare to Moxie,rather its like an improved version of Moxie where getting a KO is not a prerequisite to begin your sweep,the moment Serperior gets in it immediately exerts pressure on the opponent especially considering how easy Serperior is to get in the battle owing to the abundance of bulky waters. A simple double switch will more than often put you in a position to command the game and versus most of the bulky waters especially you have absolutely no problems predicting the incoming Crobat,Mega Pidgeot,Mega Aerodactyl especially seeing how rare Ice Beam is as a coverage move on the bulky waters that dominate the tier such as Swampert and Suicune. You might say its a 50/50 but its a 50/50 that is vastly stacked in the favor of the Serperior user,and the onus is on the player of the opposing team to make reactionary plays which more often than not will put them on the back foot. The thing that really makes it look broken to me though is how it can cripple even its best checks,leaving them vulnerable on the next switch in. Obviously the set of champions argument where Serperior has all of Taunt,HP:Fire,HP:ice,Synthesis,Leaf Storm,Substitute,holds absolutely no credence,because it obviously can't run all of those at once,but the thing is it doesn't need to. It has its niche in Contrary but it does it so well that even if you know in advance whats coming you may not necessarily be able to put a stop to it. And to those saying that it encourages a less stall-infested more prediction based metagame, I do agree to a certain extent,but do you really think that a Pokemon that almost single handedly can make Stall unviable while at the same time maintaining a great speed tier should be allowed in the UU metagame? I have already voted ban to put an end to this snake's reign of terror in UU, I only hope that you will all do the same!
