Neat little set I played with for a bit a while back. Absolutely needs Groudon and Entry Hazards to really function, but if the support is good this set is a monster. Set up a Substitute on something you will force out, like Giratina, and set up Flame Charge. While you really need 2 or more Flame Charges to really get going, the extra bulk is really good, and even without a boosting item (though you may want Life Orb to beat weakened Chanseys) you can still demolish Pokemon like Arceus and Groudon with Blue Flare.
Gonna look for my EVs on Tanky Rayquaza, I'll edit this post when I find them.
