Well, I just answered Dr. Flame's, I guess I could try this one.
Looks good, although you might want to replace Taunt with Cross Poison, as Crobat won't survive very many hits anyway.
I honestly don't know where "C" came from, as it's "Rotom- Mow. Like the strategy going on :)
This thing makes a surprisingly good wall. And staller at that. Try this set:
Cresselia (X) @ Leftovers
EVs: 252HP, 252SpDef, 4Def
I recognize this set from Smogon. I'd use Fire Blast if I were you. Change the 4SpDef to 4HP.
Looks mighty fine.
I like the team! Pretty good.
