Scott,

        If you use an Item Finder can you put the Item Finder you used back
in your hand? The text on Item Finder says discard 2 cards from your hand in
order to put a Trainer card from your discard pile into your hand. You may
think this is a stupid question cuz hardly anyone wants to discard cards for
nothin but I play Promo Mewtwo and want to know if I culd discard two psy
energy using an Item Finder and get the Finder back so I can Absorb and
attach more energy on turn 1.
 thanks for any help you have

Nope.  You may play the Item Finder without retrieving anything, but as the Item Finder is not in the discard pile when you play it, you may not use it to retrieve itself.  Sorry.
