So far I have reconstructed all the unknown WotC era commons sheets (Base Set 2, Gym Heroes, Gym Challenge, Neo Revelation, Neo Destiny, Legendary Collection, Expedition, Aquapolis and Skyridge) as well as a select sample from the Nintendo/TPCI era to make sure the cards are still inserted into packs the same way
The downfall with booster packs is you are not guaranteed Ultra rare cards and would need to purchase multiple booster packs to increase your chances of finding these cards
For the record, I have nothing against booster packs
Best Pokmon Booster Pack deal $279.99 Save $30.04 With a new price cut of over $30, pre-ordering the Pokmon TCG Mega Evolution Perfect Order Booster Display Box (36 booster packs) for $249.95 means you're only paying roughly $6.94 per booster pack
So, why wouldn't every deck want to run as many Stage One Cards as they can
