I've been messing around with a sun team on the ladder, and here are some of my thoughts:
- Sun is absolutely terrible against every other weather team
- Sun has very favorable matchups against all other teams, especially standard offense, which simply cannot withstand infinite turns of boosted-speed grass sweepers
- Speaking of which, grass-oriented offense is definitely the way to go over fire-oriented offense if you're running a sun team. I'm not saying don't have any fire type offense, but no more than one poke (entei or arcanine works well). Swasbuck is basically the kingdra of the sun, use it accordingly
- If you're using a sun team, use wobbuffet! I have no idea why I have not seen a single wobbuffet on sun teams, because it has easily been the single most valuable supporter I have used. The best position to be in with a sun team is with a +2/+2 grass type, and wobbuffet is invaluable in facilitating this.Switch into something like Slowbro, Encore its Slack Off, go to Tangrowth/Swasbuck, use Swords Dance, and proceed to fuck shit up for the next few turns. It's also great against choiced revenge killers.
As I mention above, other weather teams really kill sun because Vulpix fucking sucks, and it's very easy for the opponent to get rid of it. I've beaten other weather teams, but only when my play is simply more intelligent than my opponent. Against an equally matched opponent running hail or sand, I have little chance of winning. However, I'm mildly disturbed by how efficient and simplistic sun is against all other teams. I'm not sure if this is because people are inadequately prepared or if it's just that there are too many threats right now for every team to cover, but I will test more and offer updated impressions later.
