Energy Accelerators

[Ultima]

Oh yeah, Leafeon RR can attach basic energies from the hand with an attack.

I've been mentally playing around with the idea of comboing RR Jirachi and Flint's Willpower for 3 attachments a turn.

Lucian's Assignment gives you the ability to move any number of energy from one Pokemon to another.

 

[Ultima]

A few other things:

Stark Mountain lets you move Fighting and fire energies.

Not sure if this counts, but Heatran lvl X can recover 2 discarded basic energies from Metal and Fire type attackers.

Not sure if this counts either, but Energy gain reduces the attack costs of your SPs...

Grotle MD can use an attack to attach grass energies from the hand to anything.

Sealeo (RR) lets you search your deck for 2 Water Energy cards.

Starmie (RR) retrieves a Water Energy from the discard pile.

and the Drifblim RR that is written in the first post should be Drifblim (SF)...
