I figured as much.
Now for some Team Building Questions. I'm attempting to put together a Sandstorm Team. I had a few ideas hit my head lately. This is kind of an important note, but I always assume Item Clause is on when creating teams (unless the holder states otherwise or it's Little Cup, but I don't see Little Cup Questions in an Overused Forum, now do I?)
1. Is it a relatively bad idea to run both Tyranitar and Hippowdon in the same team, or would it help with winning the Weather War against opposing Weather Teams?
2. What are the best spinners for Sandstorm Teams? I don't want to use Donphan and Hippowdon together (Leftovers and...WHAT ELSE? o.o ), but what else is there to use for a Sandstorm Spinner?
3. My most guaranteed Pokemon on the team is Landorus-I, as it can run a mean Sand Force Set. With this Pokemon, would it be wise to run Garchomp or is it typically a war between the two as to which one gets in the team?
4. I considered Sash Alakazam. Is that a good idea?
5. Ice-Type Attacks are going to be a pain to get over. What Steel-Type should I use? I considered Heatran and Jirachi so far, and I always thought that Magnezone would be a good Revenge Killer as my Steel-Type.
6. Gastrodon sounds like a good Pokemon to use because of the amount of Rain Teams I've been seeing. Combined with Heatran, would they make good Weather Counters for my team?
7. (Swear this is the last question) If I employ a Terrakion, would a Band or Scarf set be more effective?
Sorry if the bombardment of questions is bothering you, but I needed to get these questions out so I don't continuously post anymore o.o
1. T-tar and hippo can work on the same team. You are compounding some weaknesses that you'll need to cover, and your team becomes slightly more defensively slanted. These aren't necessarily problems, just things to keep in mind building the team.
2. Starmie works fine as a spinner in sand. It can check the fighting types that prey on t-tar and gives a water resist. I wouldn't use donphan for the reasons you said. Really any spinner can be fit on a sand team, you don't need to make much special consideration. As such, forretress and even tentacruel or hitmontop can work.
3. It is not actually bad to run two sweepers walled by the same things if they are powerful enough. One of them weakens the checks/counters, and then the other punches through and takes down the rest of the team. That's the basic concept of rain offense, 4drag2mag and hyper offense. That being said, be careful of that ice weakness, make sure you don't just lose to mamoswine.
4. It can be if that's what you team needs. You need a reason beyond just "revenge killer that's immune to sand", make sure it does what you need better than anything else!
5. Heatran and Jirachi are good choices for sure, and can fill a number of different roles. OU is full of quality steel types to pick from, consider scizor and ferrothorn as well. If you just need an ice resist, then there are also a lot of good water type to consider too (rotom-w, starmie, keldeo, etc)
If you use magnezone, usually it's because you really want magnet pull. If you forsee steel types being a big problem for your team, then go for it. But if you want to stop mamoswine or fast rain sweepers, then magnezone probably won't cut it.
More importantly, don't just slap an ice resist on a team and call it a day. Figure out what pokemon and sets you are losing to, and edit your team to deal with those. This may mean adding an ice resist, but it may mean something entirely different.
6. Gastrodon and heatran used to be used a lot in bw1 as an anti-weather core. After thundurus was banned, gastrodon usage has dropped a lot though. I don't know how effective it is nowadays, my suspicion is that it simply isn't bulky enough, but try it out and see.
7. Depends entirely on what you need.
With all of these questions, just put together a team and try it out! Your own experience will be far better than relying on someone else's. If you're worried about rating, just use an alt.
