This set looks good, however it needs a lot of prediction since you never know if the opponent decides to launch an attack when you switch in. Plus, it needs a spinner to get rid of entry hazards, since physical sweepers only set up late game

You heard of Sand Veil Garchomp, now let's introduce SV Gliscor! In the Sandstorm, Gliscor's evasiveness goes to 120%. Rock Slide=30% chance of flinch. Attract/Swagger=50% chance of opponent not being able to attack. Add all this up, and the opponent has a 12% chance of attacking! Hows that for hax? If any attack does get through, sub's there to stop it, and Roost + Lefties provides healing. This guy can stall unbelievably, with Rock Slide slowly whittling down the opponent's health. Gliscor has the ability, the moves and the bulk to execute such a set, and EQ can replace Roost for more coverage and in case of a PP run out, since Lefties already provides good healing. The EVs give good bulk + enough speed for flinching.
A good teammate for Gliscor will be Jirachi to ParaFlinch, and with Paralysis factored in, Gliscor has a 3% chance to be hit!
EDIT: The rate is 29% not 12%, think I used the wrong method of calculating
