Japanese Tag Team GX sm12a Complete Set with Reverse Holos -307 Cards?? There are 173 cards in the base set numbered 001-173 of 173 cards. This set includes the reverse holos of which there are 134 cards so the total becomes 307 cards. This is not a Master Set because the Master Set would include 53 secret rare cards.This is one of the largest Japanese sets and has proven to be quite popular. The cards are near mint to mint as I pulled the majority from packs. For the most part, I find Japanese cards to be well manufactured. There are some cards where the borders are not evenly centered but overall, an excellent set! The cards will come in a Vault X binder and all cards have been sleeved before placing them into the binder. If you are truly interested, I could pull the reverse and post them separately as I currently have a 173 base card set posted without the reverse.
