Hey, guys. This is more of a discussion post to show the progression of this challenge. I'm at 5-0 with a 1869 Glicko2. I honestly feel that this challenge shows the power of UUs in OU. I am having a lot of fun with Weavile, as it is one of the few things that can legitimately outspeed Tornadus-T and one-shot it without a scarf. It can also trap Tornadus-T in their feeble attempts to regain HP. Try it out, people! I also am liking Roserade, as it is a near-perfect counter to many rain-offense teams once Tornadus has been eliminated. A resistance to Water and fantastic SpDef is a big help in beating those teams.
Here is a replay of my team crushing a Rain Offense team, with both Weavile and Roserade being stars! Enjoy, Smogonites.
