About Professor Oak (Base Set Shadowless)
Trainer card. The most famous Pokemon trainer — discard your hand and draw 7 new cards. Tournament-defining card.
Shadowless is the rare transitional variant between 1st Edition and Unlimited. It has no edition stamp AND no drop-shadow border. Printed for only a few weeks in early 1999 before WotC added the drop-shadow that defines Unlimited.
How to identify a Shadowless Professor Oak:
- No “Edition 1” stamp on the lower-left
- No drop-shadow on the artwork box edges
- Thinner card stock than Unlimited
- Sits between 1st Edition and Unlimited in rarity
