No, my hydreigon was my revenge killer. I don't have a sweeper in my team. Basically, if elements adds up, I get a KO, or else, I work around with my team to get a KO. (Well that's my strategy, but it's incredibly hard to use). And, looks like you didn't notice, but my hydreigon was in a luxury ball. (It was a wild pokemon that I had caught)
