without getting into the minutae of what has to go right and everything that could go wrong can we all agree that if you can attack with supreme blast six times you will win a pokemon match with a metaphysical level of certainty? six supreme blasts mean 12 energies discarded of the course of a game. if i run only six in my deck that means i have to have the ability to pull six energy out of my discard pile over the course of the match. there are many simple ways to do this: night maintenance, energy pickup, energy restore, mewtwo, rotom, plusle, etc. prized energy are not a particular worry either since you can easily identify these with azelf and take them as your early prizes.
