I used to collect and play mtg 10-15 years ago,I recently moved and found all my cards. I have thousands of cards 4th edition,5th edition,tempest,ice age,weatherlight,mirage,stronghold,portal,unglued. I also remember having some alliance,homeland,unlimited,3rd edition,arabian nights,legends,visions and several starter decks and decks. Would it be worth my time and effort to go through them and sell them or would i be wasting my time?
