Energy Gain is only really good if you can turn 1 Deafen on Dialga, as Belt/G is much better. E gain is only really used on Garchomp and PromoCroak, I really don't think four is worth it.
Could you drop a Bebe's? That would allow a turn 2 BTS into claydol via Roseanne's and Lux Ball...
Not that likely to happen though but possibly worth a try.
