I'm adding more to the thread in a bit, maybe you'll be interested in those. Most of them are EV trained, so if you're interested in them, they should be up by tomorrow.
The set I was planning for was:
-Toxic Spikes ("Start")
-Spikes (lvl 28)
-Rapid Spin (lvl 17)
-Gyro Ball (lvl 50)
So no, you don't need to redo it, unless you want to.
When would be a good time to trade it over?
