Orientation on tkay: You pick some good pokemon, so I give you credit on that. You also know how to pick movesets. Your team synergy (teamwork) was also decent. However, I saw some major lack points.
1. Lack of walling - Your whole team was just an offensive slaughter that could be walled by all 3 of my walls, depending on the pokemon needed. Although that move against my physical was was rough...*shudders*. Anyway, you went too offensive, and even that wasn't enough to break through.
2. Supportless - When I laid the Stealth Rocks on you, you seemed very worried about switching. You need a spinner or assemble a team that can resist stealth rock nearly completely.
3. Lack of switching - If your physical sweeper has nothing good against my physical wall, don't leave it in. That's what got it killed.
4. Lack of prediction - I could easily switch out to something resistant to your next attack. That worked against me when my Scarf'd pokemon missed its move then suffered a nasty KO crit.
Well, I won 4-0...tkay, until you can come close to me beating you at least 0-2, or if you win, or if by other reasons, I can't give you the promotion to a frontier brain. I'll let you try daily, but consider the above tips.
