Energy Manipulation.
It's what makes the world go round in this format.
See, ALL HIGHLY COMPETITIVE decks today involve SOME SORT of energy manipulation:
Gardevoir Psy Shadows.
Blaziken Firestarters.
Swampert Water Calls.
Expedition Ampharos (put into Ampharos EX decks most of the time) uses its power (can't think of name) which moves energy from the bench to the active.
Sceptile Energy Trans's.
Muk uses Roselia's speed growth.
TA Lanturn and TA Manectric are in a lot of rogue decks, and together they can do some cool shtuffz.
Kingdra Aquapolis Water Calls (usually in Kingdra ex decks).
If Boost energy counts, then that pretty much gets everything.
You need to introduce them to energy manipulation as fast as they can grasp it. It's what makes decks, so it's essential to new players. Energy Manipulation also comes in forms of certain energy:
Recycle Energy is Energy Manipulation. Revelation Kingdra just pwned other decks into the EARTH with Recycle Energy.
Entei's Howl power was energy manipulation. That also pwned during Eon. Mareep from Aquapolis, I believe, has an attack that powers it up EXTREMELY fast, depending on the number of Mareep in play, which powered Rev. Amphy back when it was F34R3D by ALL!!!
Blastoise = Energy Manipulation
Venusaur = Energy Manipulation
It's been around since the beginning of time (ie base set '99
) and it's ABSOLutely essiential. Get them introduced to the rules, then shove energy manipulation into their faces, give them a jump start, hope to see some rising stars!
