Poor (4/10)
High Investment Required
Epic Relics
Rare Relics OK
Widely considered one of the weakest and most outdated champions in the game due to high mana costs and a slow game plan. While he possesses a niche 'One Turn Kill' potential in Monthly Challenges using specific relics, his general performance is frustrated by a poor starting deck and 'archaic' star powers.
One Kick Man
  • Chemtech Duplicator icon
    The cornerstone of Lee Sin's finisher. Once you reach 6 mana, this doubles all spells, allowing you to double-cast buffs and, most importantly, double-cast his champion spell 'Dragon's Rage' for massive damage.
  • Hymn of Valor icon
    Generates 'Redoubled Valor' (3 mana). When combined with Chemtech Duplicator, you can quadruple Lee Sin's stats in a single turn before kicking the enemy Nexus.
  • Chosen by the Stars icon
    Provides Fated and Augment to scale stats rapidly when targeting Lee Sin with spells. Crucially grants Overwhelm, ensuring his Dragon's Rage damage carries over to the Nexus.

Strategy

Stall the early game until you reach 6 mana. Use cheap spells to trigger Lee Sin's barrier and challenger to control the board. On turn 6 (or earlier with ramp), cast Redoubled Valor followed by a Dragon's Rage (often from his Challenger attack) to obliterate the enemy Nexus in one sequence.
Infinite Flow
  • Perfect Hex Core icon
    Creates a 'Hex Core Upgrade' every round. This provides a consistent, cheap spell to help trigger Lee Sin's 2-spell requirement for Challenger and Barrier.
  • The Grand General's Counterplan icon
    Generates a fleeting copy of Lee Sin (which becomes his champion spell) every round. This ensures you never run out of spells to cast to maintain Flow.
  • Archangel's Staff icon
    Refills spell mana every round, ensuring you have the resources to cast the generated spells from your other relics.

Strategy

This build focuses on consistency rather than a single OTK turn. By generating cheap spells and mana every round, you can consistently activate Lee Sin's protective barrier and challenger effects to control the board while slowly chipping away at the opponent.
Rare Relic OTK
  • Chemtech Duplicator icon
    Doubles your buffs and removal spells once you hit 6 mana, enabling the 'Big Kick' win condition.
  • Hymn of Valor icon
    Provides the massive stat boost needed to make the OTK viable.
  • Troll King's Crown icon
    Grants Overwhelm to all units. Essential for ensuring that the damage from Dragon's Rage connects with the Nexus rather than just killing a unit.

Strategy

A budget-friendly version of the OTK build. Play defensively until 6 mana, then use Redoubled Valor (doubled by Chemtech) to create a massive Lee Sin and attack. The Overwhelm ensures victory.
Other Relic Options
  • Secret Technique icon
    Doubles the stats from buffs played on Lee Sin. An excellent substitute in the OTK build if you want even bigger numbers.
  • The Beast Within icon
    A strong alternative for Overwhelm that also buffs your entire board, helping with early game trades.
  • Echoing Spirit icon
    Adds copies of Lee Sin to your deck and reduces their cost, helping you find him and making his champion spell cheaper.
Constellation
Lee Sin's constellation and star powers are generally considered outdated and victims of power creep. His kit revolves around playing multiple spells per turn, but his base deck and powers often leave him mana-starved. While higher star levels (like 6-star) offer significant power, the journey there is often described as painful compared to modern champions.

    Review
    Widely criticized as 'archaic' and 'comical'. It generates a Twin Disciplines that is often not discounted enough to be fluid, leaving Lee Sin mana-hungry.

    Review
    Provides a buff when playing 2 spells, but often feels too slow or difficult to trigger consistently without specific mana-generating relics.
Gameplay Tips
Manage Mana Carefully
Lee Sin is extremely mana-hungry. Avoid tapping out for units if it means you cannot cast the two spells required to trigger his Barrier and Challenger. Often, passing the turn with spell mana banked is the correct play.
The Big Kick Setup
Your primary win condition is often a One-Turn Kill (OTK). Do not waste your Redoubled Valor or other big buffs early. Wait until you have the mana to cast them—ideally with Chemtech Duplicator active—and an attack token to execute the combo immediately.
Draft Cheap Spells
Lee Sin's starting deck is notoriously clunky. Prioritize drafting low-cost or 0-cost spells during your adventure. Powers that generate free spells or refill spell mana (like Sorcery) are top-tier picks.
Avoid Counterfeit Copies
While it seems like a spell-spam tool, Counterfeit Copies often clogs your hand and prevents you from drawing your actual win conditions. Avoid it unless you have a specific synergy in mind.
Utilize the AI's Weakness
The AI often struggles to block Lee Sin correctly when he has Challenger and Barrier. Use this to remove key threats for free while preserving Lee Sin's health.
