Hey my name is Brett Te Slaa and i have a tip that mabey no one has ever thought of.So here it is.
 
Get your Revalation Houndoom up and use Dark Flame for a dark energy then energy flow and put it in your hand. Then u can atach it to murkrow or sneaslem.This is the fastest way to get dark energy from the discard to your hand.
