Ranking the top 10 most expensive Charizard cards of all time is an exercise in navigating through decades of Pokemon history, from the 1999 Base Set that launched the hobby through the EX, Diamond and Pearl, Black and White, XY, Sun and Moon, Sword and Shield, and Scarlet and Violet generations
Both Porygon-Z cards are very good, with annoying and disruptive attacks, and being able to get there on turn 2 makes those decks much more consistent without needing to rely on Rare Candy
Theres a big difference between clearing away all threats right before you untap and playing a 6 mana board wipe after, as you usually wont have much mana left for follow up plays
This one-mana sorcery allows you to draw two cards and then discard two cards
Its not really a big deal
It's unclear what the shelf life of this expansion will be, but it does contain many cards worth getting sooner rather than later
