The Obsidian Flames secret rares everyone wants
The rarest is Charizard ex (#228), a Hyper Rare. The priciest by market value is Charizard ex (#223) at about $138.94 — so the scarcest pull and the most expensive one are different cards here.

Finishing the Obsidian Flames secret-rare run
Landing all 33 is the hard part of completing Obsidian Flames; they push the full checklist to 230 cards and a master set to 406. Most of the set's resale value sits in this 33-card band, so even a near-complete Obsidian Flames binder can be missing the bulk of its value if the secret rares aren't in yet.
