While the cards are officially called "Star", they're typically referred to as "Gold Stars" by the collecting community, given their golden shimmer
(Standard format means the cards that can be used in current tournaments.) The reason for the difference in prices is that the Japanese Pokemon community has relatively fewer collectors and more players, which leads to a higher demand for Trainer cards and playable Pokemon staple cards (cards that are used in nearly every deck) for deckbuilding, whereas the pull rates for EX cards are much better than in English booster backs
Commander Precons are a staple of any Magic: The Gathering players diet
Although higher numbers of Endurances are found in sideboards than in the maindeck, I wouldnt be surprised if decks include more Endurances maindeck already considering how much flexibility this card gives
