I'm not trying to say that this is the best revenge killer in Ubers. What I'm trying to say is that it is a fairly decent one, and it does its job. Yvetal is a better scarfer most times, but this Kyurem set does what I want it to, and that's the point.
Also webs are not really a problem, as I usually run a reliable defogger with this when I use it. Most of the times I kill Zacians with this are when I predict a switch, or when the other person has already set up.
Scarf Ditto is way better than this set at revenge killing, but like R-The-Great said, this is not a "What is a good revenge killer for Ubers" thread. This set may not be the best revenge killer in the tier, but it is one of the best sets Kyurem-White can run. (Specs on a webs team can work as well.)
If we only made sets for the very best Pokémon in the tier, there wouldn't be much on the threads for lower tier Pokémon. Just because a Pokémon is low tier doesn't mean you aren't allowed to use them, and it can be fun to make sets for Pokémon that don't see as much usage and test them out. Smogon's tiers are based on usage, so if we had good sets for low tier Pokémon, people might start using them, and they might get a little more attention.
That about sums up what I wanted to say. It's nice to see that people are willing to look at sets and consider alternatives instead of just saying: "WHitE KyUrEm iS LOw TiER DoNt UsE iT."
