You probably noticed that this question has been edited. I have seen that I only made a team of 4 pokemon and I didn't know it was against the rules...

Give Blissey Heavy-Duty Boots instead of Rocky Helmet, since it's a special wall not a physical one. If you want a Rocky Helmet user give it to Corviknight. Also, you can give Dragapult U-turn instead of Fire Blast or Thunderbolt. Specs is a good item to give Dragapult as well. You're missing 4 EVs on Weavile, Dragapult, and Nidoking. Give Rillaboom 252 Atk / 252 Spe / 4 Def and a Life Orb. You can try switching Nidoking to defensive Garchomp with rocks so you can give Blissey Seismic Toss so it isn't Taunt bait.

Please give explanations as to why you chose each team member. What do they contribute? Why did you choose the moves you did?

Hmmmmm, there isn't an exactly a specific reason why I added certain pokemon. Originally I just 4 mons. Rilaboom, weavile, dragapult and Nidoking. I was wondering what do I add to support pokemon they can't cover... Blissey and corvi were just so I could have six.

So what you're saying is that you asked this rmt without even giving the team a try?
