I just wanted to comment on how good item finder is.  Although I have not 
seen it in many decks I think it should be in many kinds of decks.  Let's say 
you have an energy denial deck.  Item Finder is perfect for this kind of deck 
because of this:
For starters lets say in your deck you have 4 Energy and Super Energy 
removals, with all that you could remove about 12 of opponent's energy (which 
is usually half the energy in a deck!) Now if you add in item finder:
You can now use item finder to get back those Super Energy Removals, 
resulting in you being able to destroy up to 20 of opponent's energy!!  Most 
decks play with about 24-26 energy cards.  That means you could destroy 
almost all of their energy!  


Besides this strategy I could think of many others that could use item 
finder.  So next time you wish you could put more than 4 of a trainer in, put 
in an item finder or 4!
