I was under the impression that all Base Set Booster Packs such as those (fanned out cards on the upper right of “Trading Card Game”) meant Shadowless Packs? I have also seen these packs feature Shadowless and 1st Ed. Un-Common Cards. However, I have never seen these packs containing Unl. Cards - does this really exist?
By no means am I an “expert” on these packs - I have only ever opened a few myself. Would love some clarification - THANKS!
