Hi, I have yet to read anywhere about possible Pokemon card misprints. My son noticed odd things about two of his cards. 1 - He has two different Tangelas, one has greenish tentacles, the other has bluish tentacles. Was this done on purpose? 2 - He also has two different Voltorbs. In the description at the bottom of the card, one makes reference to a "Monster Ball", the other to a "Poke Ball". Other than that the cards are identical. If you have any info on this, it would be appreciated. Thanks, Steven Hare
