Excellent (9.5/10)
Low Investment
Rare Relics OK
LeBlanc is universally recognized as one of the most powerful 3-star champions in the game. She excels at aggressive, infinite-combo strategies and requires minimal constellation investment to clear the hardest content.
Endless Strikes
  • Chosen by the Stars icon
    Provides massive stat scaling and essential keywords (Overwhelm, Challenger, Regeneration) once LeBlanc reaches 10 power, which is easily achieved through her 0-cost Mirror Image spell.
  • Stalker's Blade icon
    Triggers an immediate strike upon summon, allowing LeBlanc and her ephemeral copies to clear the board instantly.
  • Stalker's Blade icon
    A second copy doubles the strike effect, ensuring that every Mirror Image cast removes two enemy units.

Strategy

This build focuses on maximizing immediate board impact and aggressive scaling. By repeatedly casting the 0-cost Mirror Image spell, LeBlanc summons ephemeral copies that trigger double Stalker's Blade strikes. This rapidly clears the enemy board while simultaneously buffing the original LeBlanc to activate the Empowered 10 threshold from Chosen by the Stars.
Infinite Value
  • Echoing Spirit icon
    Creates 7 copies of LeBlanc in the deck, ensuring a high density of champion cards to receive random Epic items.
  • Guardian's Orb icon
    Grants Epic items to random cards in the deck every time LeBlanc or a copy is summoned.
  • Guardian's Orb icon
    Doubles the item generation, rapidly scaling the power of the deck.

Strategy

Players disagree about Guardian's Orb on LeBlanc. Some consider it a highly effective scaling tool that leads to explosive, game-winning combinations, while others view it as an unnecessary gamble compared to direct damage. This build leans into the scaling potential, using Echoing Spirit to ensure the generated Epic items consistently land on LeBlanc herself. Repeatedly summoning ephemeral copies will quickly fill the deck with powerful, item-stacked champions.
Immortal Clones
  • The Taker's Bow icon
    Prevents attacking Ephemeral allies from taking damage or dying, completely neutralizing the primary drawback of LeBlanc's clones.
  • Galeforce icon
    Grants Scout, allowing the immortal ephemeral clones to attack multiple times per round.
  • Stalker's Blade icon
    Provides immediate board control upon the clone's summon before the attack phase begins.

Strategy

This premium build utilizes The Taker's Bow to fundamentally alter how LeBlanc's ephemeral copies function. Because the clones no longer die when striking during an attack, they can safely utilize the Scout keyword from Galeforce to generate multiple attack tokens. This creates an overwhelming board state where ephemeral units continuously pressure the enemy Nexus without expiring.
Rare Relic Aggression
  • Stalker's Blade icon
    Provides immediate removal upon summoning LeBlanc or her copies.
  • Stalker's Blade icon
    Doubles the removal potential, allowing for consistent board wipes.
  • Guardian's Orb icon
    Adds long-term scaling and value generation to complement the immediate strike damage.

Strategy

A highly accessible and devastating build that relies entirely on Rare relics. The dual Stalker's Blades ensure that every Mirror Image cast translates into significant enemy board disruption. The Guardian's Orb provides a secondary win condition by stacking items on the deck, ensuring that even if the initial aggression is stalled, the deck scales out of control in longer encounters.
Other Relic Options
  • Secret Technique icon
    Doubles the stats granted by the Mirror Image spell, allowing LeBlanc to scale her power rapidly.
  • Death's Foil icon
    Ensures LeBlanc survives her attacks, which is crucial for generating the Mirror Image spell safely.
  • The Beast Within icon
    Provides Overwhelm and a stat boost, serving as a reliable alternative if Chosen by the Stars is unavailable.
  • Scales of Judgment icon
    This relic is a trap for LeBlanc. It triggers on 'Play', meaning her summoned ephemeral copies will not activate the strike effect.
  • The Curator's Gatebreaker icon
    This relic is a trap. Due to mechanical changes altering its trigger from 'Summon' to 'Play', it no longer functions with LeBlanc's ephemeral copies.
Constellation
LeBlanc is exceptionally self-sufficient at 3 stars and does not require further constellation upgrades to dominate the hardest adventures. Her base kit provides all the tools necessary for infinite combos and rapid victories.

    Everywhere, Everyone

    +1 Starting Mana. If you've leveled a champion this game, when allies attack, summon an attacking Ephemeral LeBlanc.
    Review
    Provides unique utility when LeBlanc is used as a support champion, as it generates a copy of her even when the main champion levels up.
  • Icon for Deceptively Deadly II

    Review
    This is the critical power spike. Reducing the cost of Mirror Image to 0 mana is essential for maintaining tempo, enabling infinite summon loops, and triggering relic effects multiple times in a single round.
Gameplay Tips
  • Prioritize Level 30
LeBlanc's strategy relies heavily on equipping multiple rare or epic relics to maximize her summon triggers. Reaching level 30 to unlock all relic slots significantly increases her consistency and combo potential.
  • Protect the Main Champion
LeBlanc's deck is highly dependent on her presence on the board. Avoid taking unnecessary risks with the original LeBlanc during combat; instead, use her ephemeral copies to execute dangerous attacks and clear blockers.
  • Seek Rally Effects
Powers or items that grant Rally (such as Domination or a Rally banner item) are the primary win condition. Because LeBlanc can generate 0-cost copies of herself, a Rally effect allows her ephemeral copies to attack endlessly in a single round.
  • Understand Capture Mechanics
If LeBlanc captures an enemy unit and then creates an exact copy of herself, the game copies the capture buff. This immediately releases the original captured unit due to how the game processes duplicate capture auras. Plan around this intended interaction when drafting capture-based powers or items.
