In response to the comments on December 3rd (Re: Cards That Hardly See the
Light of Day 11/27 - Patrick), I would disagree that Devolution Spray
doesn't have a use, if used properly.

One of the decks I play is a Dark Vileplume/Muk/Dark Muk deck.  It is
wonderful to see your opponenents eyes glaze over when they see Dark
Vileplume take the bench - because outside of the 15/3 environment, decks
are still trainer-heavy.  The one down side of this is that you cannot play
trainers.  However, thanks to Muk's Pokemon Power and Devolution spray, you
can!

Muk's Pokemon Power prevents all other Pokemon Powers from working.  So
evolve a Grimer into a Muk, and you can use all the trainers you'd like! 
However, that leaves your opponent able to use his trainers on his next turn
too.  The solution - play all of the trainers you can that have accumulated
in your hand and before you attack - play Devolution spray on Muk!  Thus
you've emptied your hand of trainers, gotten everything you can out of it,
and your opponent is still left with a handful of useless trainers.

Another use would be as following.  Have your Dark Vileplume active, and use
Dark Gloom's Pokemon Power.  Should you fail, your active pokemon becomes
confused - thus Dark Vileplume's Pokemon Power stops working.  Again, you
can use all of the trainers you want, finish up with either a Switch or a
Devolution spray - moving Dark Vileplume to the bench or devolving cures the
confusion.  If using Devolution spray you can now retreat or Switch Dark
Gloom back to the bench, and before attacking, evolve back up to Dark
Vileplume - again leaving your opponent unable to use trainers.

Hope these tips help show that Devolution Spray DOES have some uses.
