Err... This looks like an in-game team to me... Competitive teams are generally lv100 (50 for VGC, 5 for LC) for use in wi-fi battles for a specific competitive tier as defined by Smogon (or Nintendo, in the case of VGC)
"Whether Castform the Weather Pokemon can weather the weather is dependent on whether the weather that it's weathering is the proper weather for it to weather. Whether the opponent can weather the weather is also subject to whether the weather that it's weathering is the right weather to weather. Whether Castform can weather the opponent is once again dictated by the weather and whether that weather is the favorable weather for weathering. But most importantly, you should know whether there will be weather to weather rather than what weather they will be weathering and whether they can weather that weather."
