Obsidian Flames Card List: The Hidden Gems Traders Are Secretly Using in Genshin Impact


If you’re a savvy Genshin Impact trader or a fabricated deck enthusiast, you’re not just chasing the newest cards—you’re hunting for undervalued gems that can turn the tide in battle and boost your collection’s worth. One mysterious but powerful deck theme gaining traction among veteran traders is Obsidian Flames—a high-damage, fast-paced deck built around obsidian-themed cards with intense elemental synergy.

Understanding the Context

But here’s what most don’t know: the true secret to this build lies deep in its card list—a collection of often-overlooked but critically powerful cards that quietly dominate fight performance and rarity grading. In this article, we break down the Obsidian Flames Card List: the hidden gems traders are secretly using to maximize value and edge in both PvP and deck-building circles.


What is the Obsidian Flames Deck?

The Obsidian Flames deck uses the signature obsidian core-blunt and elemental-on-element stacking of this theme—generating explosive AoE burst damage through combos with tri-digit attacks, AoE buffs, and explosive elemental combos. Often featuring Lesser Demi-Orbs, Obsidian-based traps, and flame-heavy pyro synergy, this deck excels in speed, area control, and damage output, making it a favorite for aggressive, high-accuracy playstyles.

Key Insights


The Hidden Gems You Should Add to Your Obsidian Flames Card List

While many traders focus on flagship loadout cards, the most underrated gems in this deck are lesser-known but game-changing cards. These are the ones quietly fueling the fastest, most efficient trades:

1. Obsidian Mask of Destruction

A cheap amplifying artifact but critical for card draw and survival—its shadow merging buff enables repeated casts that fuel combos. Not just a product shield—it’s a mana funnel and mobility enhancer that’s often overlooked.

2. Lesser Demi-Orb: Obsidian Wrath

This card creates a devastating AoE shower when activated at full force, synergizing perfectly with Obsidian Flame’s bullseye elemental burst. It’s not just a steady damage dealer—it’s a game-saver in prolonged battles.

Final Thoughts

3. Pyro Obsidian Maelstrom

A pre exile card with slow but massive burst AoE flaming damage. When timed correctly, it turns into the ultimate crowd control tool that secures kills and enables consistent card play.

4. Obsidian Spike – Reibeaping

Used as a suppression and damage card, its shard-stacking AoE mirrors make it ideal for scaling group fights. Rare in ‘hidden gem’ tier but perfect for aggressive rune reuse.

5. Obsidian Core-Blunt (Slicing Form)

Many players miss the trap variant, but the Slicing Form unleashes devastating zone damage with high critical chance—ideal for cleaning waves and synergizing with demons like Sucrose or Vaeya for explosive combos.


Why These Cards Are Secret Traders’ Choices

Teams relying on Obsidian Flames aren’t using flashy starts—they’re focused on efficient damage multipliers, consistent steam, and low-cost entry cards that compound into winning momentum. The hidden gem cards listed above:

  • Reduce turn reduction through meta-synergies
  • Increase sustain with shielding and mana shield effects
  • Enable consistent card draws to fuel combos
  • Lower overall material cost, making trades more profitable and repeatable

These aren’t top-tier ‘1-tier’ cards you’ll see on top stream decks—they’re precision tools hiding in backline slots, quietly transforming Obsidian Flames from a flashy deck concept into a dominant, repeatable win condition.


How to Build Your Own Hidden Gem Obsidian Flames Deck

  1. Prioritize Archetypes with High Burst and AoE — Lesser Demi-Orbs, Obsidian Maelstrom, and Thrive tracks.
  2. Scaffold Defense with Utility Cards — Obsidian Spike for crowd control, Obsidian Mask for card draw.
  3. Layer Pyro Ecosystem — Use heat synergy cards to amplify AoE damage without stacking cards.
  4. Optimize Grievancy or Hammer for Recovery — manage trades with cards that scale sustain.
  5. Test and Tweak Based on Counterplay — Obsidian Flames thrives in fast-paced metas; adjust rune builds to counter prevalent builds.
