Thanks, I'll definitely add mixmence and mixkyube, the reason I showcased Kyurem-B with a band in the OP was that is was one of the best examples of sheer power in the metagame. I will make sure to include mixkyube in the mixed attacking gallery and possibly the sub/roost/claw/tail set somewhere else as well.
Also this thread is about wall breaking in general, you're free to discuss counters and strategies as well as simply posting wallbreaker sets, talk about the metagame and the importance of this type of offence etc. Personally the reason I think stall has been having so much trouble lately is because of the fact that a lot of offensive pokemon are pulling double duty. A lot of pokemon who are strong and fast can break walls and sweep offensive teams because many more pokemon are going mixed in this metagame.
I warned you about stairs bro! I told you dawg!
