No one ever thinks of anything good in a deck with this great trainer.
But Impostor Professor Oak is just perfect in energy removal decks.  I
mean, 4 ER's, 4 SER's, an 4 IPO's would just kill.  See, IPO would just
make your opponent discard more cards in his/her hand, including
energy!  Just keep on using it and the other trainers, and you'll kill
off so much of your opponent's energy.  Let's say that most players use
a little less than half of their deck as energy.  So your trainers,
altogether, theoretically, could kill off about 26 energy, if only half
the cards in your opponent's hands were energy every single turn.  and
the opponent had seven cards in his/her hand.  Most people are scared
that the enemy will get good cards that they want.  What can they do
with them without energy?  And they'll be losing other good cards, too.
Also, You can make the other guy deck him/herself.  You can destroy,
with all your trainers, a maximum of 40 cards.  Whoah.

Thanks for posting this, if you do.
