My brother noticed a cool combo when using Darkness energy and
Venomoth.

Using Venomoth's pokemon power: Shift, you could make him the darkness
type if you had one in play, then lay some darkness energy on him to do
a
really damaging, but energy intensive Venom Powder atttack.  Who knows,
20 or 30 damage, confusion, and poison!?!?  throw in the free retreat,
and you've got a killer
that will really screw up your opponent quick, if you don't want to put
the darknesss on sneasel, seeing that it's the only darkness worth
playing.
