An Obsidian Flames master set is 406 cards — every card plus its 176 reverse holos.
What an Obsidian Flames master set includes
One of everything: all 230 numbered cards — the 197 base plus 33 secret rares — then every reverse holo, 176 of them. That sweeps in the 18 Illustration and Special Illustration Rares, the full-art cards that carry most of the value. The ones you have to land:
- Charizard ex (#223) — Special Illustration Rare (~$138.94)
- Ninetales (#199) — Illustration Rare (~$48.07)
- Charizard ex (#228) — Hyper Rare (~$46.27)
- Cleffa (#202) — Illustration Rare (~$45.26)
- Gloom (#198) — Illustration Rare (~$28.36)
- Pidgeot ex (#225) — Special Illustration Rare (~$24.18)
The extras unique to Obsidian Flames
Obsidian Flames has no special pattern variants, so the master set is the 230-card checklist plus 176 reverse holos — no extra pattern foils to chase beyond the 33 secret rares.

The Obsidian Flames master-set total
All in, a complete Obsidian Flames master set is 406 cards versus 197 for the base — about 2.1× the work, or roughly 46 pages in a 9-pocket binder. Sleeve and storage budget should target the larger number if you're going all the way on Obsidian Flames.
