- Is the team built in a way so that our focus pokemon, Omastar Shell Smash, is functioning at its best?
To be honest I've never swept with omastar using this team. It doesn't seem to play much of a part in this team.
- What are problematic threats to the team (defensive or offensive) that we missed?
I found regenerator cores such as amoongus and alomomola problematic to the team, as they are capable of switching around the team, constantly regaining health and chipping away with toxic.
- What kind of small tweaks can be made (moves, EV's, etc.) that could make the team better?
Maybe run ice beam over thunderbolt on lanturn to finish off weakened amoongus.
- What is the best pokemon on the team? Correspondingly, which one is the worse?
The best pokemon on he team in my opinion is emboar. It acts as a very strong glue keeping the team together; acting as an excellent sleep absorber and revenge killing threats.
On the other hand the worst pokemon is torterra. I don't feel it does as much work as it could all it seems to do is set up rocks and let's uxie set up on it
- What would be your own "personal flair" that you would add to the team?
I would replace torterra with support druddigon. As it not only sets rocks but also fazes.
