Gust of Wind and Switch are the 2 of the best common trainers in the game 
right now.  Gust of Wind is a NASTY card.  Say your playing fighting and have 
Hitmonchan as your active.  You gust for their electabuzz and smash it down.  
Draw your prize, thanx to gust.  Now, Switch is VERY underrated.  Most people 
think they should either just retreat, or use scoop up instead.  Well, there 
is one very important reason to use switch instead.  Switch doesn't require 
discarding energy.  This is very important, because you can now play 25 or so 
energy, whereas with scoop ups, you would have to play like 28 or so.  I play 
3 of both of these cards in my haymaker deck, and it is VERY VERY good.
