Tropical Beach - Set: BW Black Star Promos
Top 10 in Top 20 Strongest Pokemon Cards
Anyone who is familiar with cards like Professor's Research will get a glimpse of what made Tropical Beach so powerful, but in order to properly comprehend why it had such an influence, further investigation is required. The ability to draw seven cards per turn was extremely powerful, and it was difficult to obtain a duplicate of the deck itself.
As soon as it was made available to the public as a promotional incentive at Worlds 2011, it saw heavy use. As a result of the high demand and limited supply, many players were forced to settle for less than a full playset, and the card was eventually banned in Japan in 2013.
