There are a lot of good cards in this set, but this one seems like it has a lot of potential.
The ability lets you move any basic energy to your active any time during your turn. It's a lot like Dragonite EX in that you can get an attacker with a bunch of energy out of nowhere, but in this case, the attacker can be anything and you can use the ability any time. Of course, it's downside is that it's a stage 2 and it doesn't have the built in switching that Dragonite comes with, but I still think there's a lot of potential for some new archetypes. The big one is Mega Manectric which can get a bunch of energy into play and then conserve it with retreat/max potion shenanigans (it has free retreat so it's perfect). There's also Victini EX which has a similar function but it gets energy from the deck. For expanded, Ho Oh EX could be even more ridiculous than it already is. And for any deck it's in, a switch/escape rope/keldeofloatstone can basically turn into a scramble switch.
