THIS. People should use it more, this set is awesome at crippling stall. Best Trick/Switcheroo user imo. NO-ONE expects it. Although I'd personally use a Choice Band since Ambipom already has amazing speed, and a CB Retaliate is going to destroy most opponents.
I decided to Trick Scarf because my team is generally pretty fast anyway, and the majority of the things the Switcheroo cripples (lots of ferro, forre, scizor, metagross, skarm, [-physical steels and ghosts here-]) are slower than my team even with a Scarf, where as Switcheroo'ing CB to something that might be able to use it could bite me in the ass. I can see the benefits of both choices.
I've been trying out Low Sweep over Retaliate specifically because I have Heatran issues. Low Kick would have also been nice, but sadly it's illegal with Switcheroo. At least Sweep gets the Tech boost though.
It really is a fun set to use. I encourage anyone that hates annoying Ferrothorn and Chans/Bliss and the like to try it. It even works well in OU!
Some fairly typical OU switch-ins:
- Gliscor loves having his Toxic Orb taken before Poison Heal activates.
- Scarfed Conkeldurr is stupid easy to deal with.
- Most Jirachis don't like being Scarfed.
- Jellicent is a very likely draw on the Fake Out lure, and it HATES being Scarfed.
- SubSplit Gengars (the more popular ones imo) lose most of their use with a Scarf.
- All your typical defensive pivot Pokemon that you would likely switch in to an Ambipom Fake Out don't like being Scarfed.
