You are so Nubfly these days, not to mention Slowfly and Drunkfly :P
This can work, but it's a bit dumb to be honest with you. And you didn't make it, a guy on Smogon made it and used it successfully in their first tourney :P
Landorus will be annoying. Intimidate will screw you, and an Earthquake / Stone Edge will screw you. Then U-Turning into a Ghost type / resisting type will make Reversal rendered useless.
Gliscor, with the Defence to wall you. Toxic stall will screw you. Subtect sets will basically play with you. Setting up a sub then Protecting will ruin your attacking power, and an Equake will just activate the FS.
There are loads more freaking counters to this, I won't spend my time and your time listing them all, but you get the point. Stall and Hyper Offence screws this over.
