Classic Collection base set Charizard is Celebrations most expensive card ($190) The biggest and most valuable chase card in Pokemon Celebrations is the Charizard from the Classic Collection, which is a reprint of the original Base Set Charizard from 1999
At auction, this card was sold for $12,900 in April 2019, and a Mint 10 version of it sold for 50K in July 2020
Gyome, Master Chef is a nice inclusion as a sought-after reprint, as is Nether Traitor, and there are essentially a bunch of great cards to slot into any deck with access to green, black, or both
All sorts of different types of decks want this card, and now they have better access to it at cheaper prices
Since these are modal double-faced cards (MDFCs for short), I figure they should be covered together
