Epic Relics
Master Yi is an exceptionally powerful champion capable of consistent early-game victories. He functions as a highly effective technician who excels when paired with specific powers, though his animation-heavy playstyle requires careful turn management.
Infinite Strike
Zoe Specialized
  • Chosen by the Stars icon
    Provides the necessary Overwhelm and Challenger keywords to bypass enemy blockers and deliver a lethal strike directly to the Nexus.
  • Echoing Spirit icon
    Ensures Master Yi is drawn consistently and reduces the cost of his champion spell, which is critical for enabling continuous casting loops.
  • Secret Technique icon
    Doubles the stat gains from Wuju Style and Twin Disciplines, accelerating his scaling to lethal levels.

Strategy

This build focuses on achieving a one-turn kill and is highly effective for the 10-star Zoe adventure. Echoing Spirit guarantees access to Master Yi and reduces the cost of his champion spell.
By repeatedly casting Wuju Style and Twin Disciplines, Secret Technique doubles the stat output. Meanwhile, Chosen by the Stars ensures the accumulated power translates into Nexus damage via Overwhelm and Challenger.
Monthly Challenge Sweeper
  • Troll King's Crown icon
    Ensures all accumulated stats bypass enemy blockers by granting Overwhelm to the entire board.
  • Crownguard Inheritance icon
    Provides a Rally when Master Yi levels up, allowing for an immediate follow-up attack after he has gained significant stats.
  • The Chameleon's Necklace icon
    Creates additional copies of Master Yi in the deck at game start, significantly increasing draw consistency.

Strategy

A highly consistent build designed for Monthly Challenges, particularly those with spell cost reductions like 'The Price of Progress'. The Chameleon's Necklace ensures Master Yi is drawn early.
The core strategy revolves around chaining discounted spells to rapidly scale his stats and trigger his level-up. Upon leveling, Crownguard Inheritance provides a Rally for an immediate follow-up attack, while Troll King's Crown grants the necessary Overwhelm to push lethal damage through enemy blockers.
Mono Spell Speedrun
  • Searing Brilliance icon
    Enables a highly focused strategy by allowing players to cut existing spells from the deck, ensuring consistent access to primary buffing spells.
  • Secret Technique icon
    Maximizes the value of every spell cast, allowing Master Yi to scale rapidly without needing to summon additional units.
  • Chosen by the Stars icon
    Grants the essential keywords needed to convert Master Yi's massive stats into a decisive Nexus strike.

Strategy

This setup is designed for speedrunning by creating a mono-spell deck. Searing Brilliance allows you to remove unnecessary spells, guaranteeing that you only draw your most impactful buffs.
Combined with Secret Technique, this creates a highly focused spell-casting engine that rapidly scales Master Yi without cluttering the board.
Other Relic Options
  • The Beast Within icon
    Grants Overwhelm and additional stats to subtype allies, significantly enhancing Master Yi's damage output.
  • Hymn of Valor icon
    Offers a massive stat multiplier that synergizes perfectly with Master Yi's inherent scaling for consistent Turn 3 wins.
  • Lost Chapter icon
    Provides immediate spell mana upon summoning, which is highly valuable for accelerating early-game spell combos.
  • Lux's Incandescent Baton icon
    Can tutor Fallen Student to generate Grief's Lesson, but is generally considered dispensable compared to relics that directly multiply stats.
  • Chemtech Duplicator icon
    Considered a trap option. Spells copied by this relic do not count as being 'played' from hand, meaning they fail to trigger Master Yi's inherent synergies.
Constellation
Master Yi reaches a massive power spike at 3 stars, capable of clearing the most difficult adventures. Further constellation investments are powerful but often considered unnecessary for his core strategy, as his base kit is already exceptionally strong.

Gameplay Tips
  • Prioritize Cost Reduction
Seek out powers like Spellslinger or Wild Inspiration. Reducing the cost of Master Yi's spells is the primary win condition, enabling continuous casting loops that scale his stats to lethal levels on the first turn.
  • Manage Hand Space
Wuju Style draws a champion card upon use. If your spells are not discounted to zero mana, continuously casting it will quickly fill your hand and cause subsequent drawn cards to be obliterated. Plan your spell sequences carefully.
  • Mono-Spell Drafting
When utilizing Searing Brilliance, avoid drafting additional spells and cut the existing ones from the deck. This guarantees consistent access to your primary buffing spells. Additionally, avoid items that summon champions when casting spells, as this interferes with summoning spirits.
  • Overcoming Revive Mechanics
Against encounters with revive or replay mechanics (like the 10-star Zoe adventure), Overwhelm and Challenger are insufficient for a single-turn victory. Prioritize acquiring powers like Double Strike or Shadow Totem to ensure lethal Nexus damage through multiple strikes. Spellshield is also crucial for survivability.
  • Beware of Stuns and Tax Effects
Master Yi is highly vulnerable to stun mechanics, which completely neutralize his single-unit scaling strategy. Additionally, encounters that increase card costs or penalize playing multiple cards in a single round will severely disrupt his game plan.
