LeBlanc
View on WikiLeBlanc is the strongest 3-star champion in the game, rivaling many 6* champions at full investment. Her ability to infinitely loop 0 cost Mirror Images to clear even the largest enemy boards is one of the most overpowered effects in the game, requiring only Leblanc being alive on the backline.

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.

Triggers an immediate strike upon summon, allowing LeBlanc and her ephemeral copies to clear the board instantly.

A second copy doubles the strike effect, ensuring that every Mirror Image cast removes two enemy units.
Strategy
This build focuses on clearing the board, then attacking with overwhelming force. Once Leblanc hits 15 power, which is relatively easy to achieve between Chosen by the Stars, Sharpened Resolve, and items on Leblanc, she can infinitely cast Mirror Image.
Each Mirror Image causes the ephemeral Leblanc to strike for 15 damage twice, creating another 0-cost Mirror Image that can be replayed until the enemy board is completely clear. This can be repeated whenever the opponent summons a unit and even if Leblanc is stunned.

Doubles the stats granted by the Mirror Image spell, allowing LeBlanc to scale her power rapidly.

Provides Overwhelm and a stat boost, serving as a reliable alternative if Chosen by the Stars is unavailable.

Makes each Mirror Image play grant random epic items to her deck. Notably, last-breath-rally on Leblanc lets level-2 Leblanc infinitely rally because she every time she attacks, she creates an ephemeral copy of herself, which strikes, dies, rallies.
In general is less consistent than Stalkers Blade because it relies on item RNG and the AI can stop the infinite rallies by stunning the ephemeral attacking Leblanc or just having units too big to safely attack into.

- Protect the Main Champion
LeBlanc's deck is highly dependent on her presence on the board. Try to bait out enemy removal spells to keep her alive.
- Last Breath Rally
If you find the last-breath-rally item in a champion-item node, take it because with it, Leblanc can infinitely rally with her ephemeral clones dying every time she attacks.
