eif baby pokemon booster box Pokémon 4.0 Collection (Chinese) – CromaTCG These cards are in Chinese language and come in a box configuration Eif Baby Pokemon Booster Pack

Like a lot of original Kamigawa block cards, they play best with the somewhat parasitic mechanics of those sets

PSA 10 copies trade at real premiums over raw

As for what cards you want to collect to upgrade, Id recommend picking up 5,000 Years in the Future packs

It adds instant perceived value and keeps your card pristine from the moment it arrives

Theres very little value in here, either financially or gameplay-wise

As for the card prices, you may be able to put some extra dollars/pounds onto the prices shown when selling them but they are not massively rare cards so I would personally advise not to sell them for too much
