Base Set Black Triangle Error

The Black Triangle error Base Set Booster Pack is a rare and collectible mistake from the early days of the Trading Card Game. These packs originally had a "1st Edition" stamp, but the stamp was covered with a black triangle to designate them as Unlimited Edition. The black triangle variant was produced for a short time, making them highly sought after by collectors due to their rarity and the historical significance of the production error. Despite the error, the cards inside are standard Base Set Unlimited cards.

Booster packs are offered in both "Light" and "Heavy" variants. A Heavy pack is defined as a booster pack that is expected to contain a holographic card or better. While pack weighing is widely accepted within the collecting community, it is not an exact science, and in rare cases, a pack identified as heavy may not contain a holographic card.

Heavy packs will be clearly labeled in the dropdown menu as [Pack Art] (Heavy). Any pack not labeled as such should be considered Light and is unlikely to contain a holographic card.
