Wanted to post on my current progress with Articuno and Swampert. I have had 14 battles, and Articuno is surprisingly powerful. I've actually been able to sweep teams with it, the only problem is keeping stealth rock of the field. If stealth rock is up, I have to force a free turn on something like Dragonite or Gliscor, since no one expects agility from Articuno. Swampert has been doing really well, people expect him to set up rocks and be a tank, but with choice band, I'm getting a lot of surprise kills on pokes. I'm running it in tandem with Choice specs Politoed, which has also been getting loads of surprise kills, since, like Swampert, people expect the defensive version. It has gotten me to 1600 ranking and I'm slowly climbing. Don't know if the team can get high enough for hall of fame, the team probably needs some adjustments, but it's been real fun to use so far and been doing far better than I expected :).
A few replays for those who wants to see the team in action:
Edit: if someone wants to help out with the team, just pm or reply here. Help is always appreciated ;).
