Many cards in Avatar: The Last Airbender are straight-up payoffs for playing lessons
Developed in Japan, the first Pokmon Trading Card Game was based on the 1996 Pokmon Red, Blue, and Yellow Game Boy by Nintendo
Typically from a mix of three channels: Japanese exporter-retailers with international storefronts (the backbone for recurring volume), marketplace and proxy-buying channels (for gaps and small test orders), and Japanese auction or buyback channels (for opportunistic and out-of-print buys)
Instead, rarity served as a soft cap, allowing players to accumulate far more commons than rares, while preserving the design intent of the set
It's still good today, and although on the Reserve List, it's just $2.49 over at coolstuffinc.com right now (Hint, hint)
Not all the best Pokmon cards have monstrous HP stats, but having lots of hit points definitely makes a card better
