If it's a good build, yes. Otherwise, no. I'd think the same with Flyphan, but not as much. Sadly, neither deck works well without Claydol and Roseannes. Vilegar, Magnegatr, Gyarados, and
possibly Charizard and Jumpluff.
No, too slow for not a huge amount of damage. After Roseanne's and Claydol, this deck just doesn't go quickly enough to outspeed much. It loses to Gyara, which outspeeds it, Jumpluff, which outspeeds it, and, of course, Magnegatr, which just mows through it.
The trouble is that Flychamp could only just about cope with Luxchomp when it had Claydol. Right now, SP is just going to outspeed it. You'd be better trying Machamp with something like Kingdra.
