To the starter of this thread, fantastic ideas. I found something similar on smogon, but I found the same strategy with cressilia for mesprit. Who is...not so hot on defenses as Cressilia is.
If I were to use strategy, no matter how much it's guaranteed to win, should I have max IV's for every stat I bother putting EV's into? Because it'd be such a burden to SR for Cressilia to have a max IV in defense, special defense, HP, AND to have a bold nature. Same for the heatran, for the stats that are most important to it.
