I'm afraid I share the same sentiments with Bluewind. The Substitute + Stun Spore just doesn't work in my opinion. I even gave Beautifly a fair test, but its lack of bulk and deceptively slow speed made it nearly impossible to set up a Substitute.

Please don't take offense to this, but those logs didn't really prove anything. Log #10 for example shows your opponent switching a Rhyperior into Beautifly when he could have switched in Drapion or even Hitmontop and then Drapion. Other times, that Beautifly didn't really do anything useful, and I found that the offensive set would have been more useful in those situations. I appreciated the bolding so thanks for that.
