>>17559155One of those has some sort of strategy written. The other one doesn't even look like those pokemon work together.
>>17559549That's kind of the purpose of Ubers, though. Legendaries banned to it are legendaries that are, most of the time, too powerful to play with regular pokemon. Ubers is sort of a battle of titans tier.
Meanwhile there are legendaries that actually are a handicap for your team if you use them, such as Regigigas for example. Just try using it in an upper tier.
>>17559857Same case as Volcarona. Its megas are too good to be eclipsed by rocks. They are good enough to deserve Rapid Spin/Defog support.
