Yeah, I'm sure it's good with something. I don't think we're getting both cards in GE, though. Just more good cards we aren't getting =/
Call Energy ends your turn...
Pachirisu/Phione wouldn't work in today's environment, when a Blissey can T2 your Pachirisu before you can even start evolving your bench with Phione. Also Gallade would take easy prizes once you bench your Pachirisu/Phione and start attacking with something else.
So Pachirisu takes the Boosted hit and you promote Phione, Celio for a stage 1 and Phione for the stage 2.
If Blissey now KOs the Phione right away you have a set up stage 2 and at least 2 KO's worth of Scramble Energy active. And that's one Boost Energy out of the way.
So how is this bad, exactly...?
Because you won't always have a celio on T2 and you won't always have a scramble on T3, and you won't always have the energy for a T1 and T2 drop. Your whole "strategy" would happen very rarely with all the other instances where you didn't end up with that perfect hand causing you to lose.
Setup decks have little chance of getting started with Blissey, Magmortar and G&G running rampant...
