Another Felix

The thing is Rotom's kinda in the Speed Deadzone for Trick Room so I don't really suggest it unless you really really need it to fit a role you just have to have. It's too fast for Trick Room at 86 base, but, it's not fast enough outside of it. It sits in a valley where it can't be really quite that effective. It also has the issue of getting no good priority that it can abuse to stay relevant in Trick Room or outpace it's somewhat poor speed.

My friend suggested switching Rhyperior to someone who can switch into an Earthquake.
