Of course gathering a sample size large enough to feel confident in that data could be a challenge - nevertheless, the card comes in as the 7th most expensive card in the set, after being a big part of the TCG during the Sun & Moon era
The initial release faced some challenges with limited supplies, but subsequent sets have improved accessibility, allowing more players to enjoy this addictive game
Its attacks are nice and perfect to fit into any deck due to its versatility in being a colorless type: Rule the Region (for three colorless energies) has a base 200 damage and can recharge up to 3 energies from your deck for your Pokmon -V as you wish, being extremely powerful, compensating any steep Pokmon (like Gengar-VMax, Lucario-VStar, etc) and/or speeding up other more versatile Pokmon
With the release of each new set, and especially when rotation occurs in the fall, the format has the potential to change as new decks are created, card synergies are discovered, and the popularity of decks wax and wane
I look forward to building with this and discovering all the many places you can use this well
