Strategy
Druddigon or Kangaskhan for early tanking while you load energy onto Darkrai.
Use Magneton's Volt Charge to gain Electric energy before evolving to Magnezone.
If you have two Darkrai's you can even use Dawn to get 40 Damage before you use an attack by putting your energy to the benched darkrai and then get dawn to move one energy to the darkrai on the active spot.
