I think you will be ok as far as fitting in. Im 37 and I know there are some older than me. As far as the decklist goes, the reason that there is set requirement on pokemon and not on trainers is because many of the trainers have been reprinted in several set, some in current modified and some not. You are still able to use the old trainers as long as the reprint is exactly the same in text. Examples are Copycat, switch potion, energy search, pokeball,etc. One example of a card that has been reprinted but is not legal to use in old form is Steven's Advice. Reason being is there is a slight text difference. Look me up on Sunday in St. Louis Park if you decide to go. I am very easy to find in a crowd. Look for a guy pulling luggage full of cards behind him.
