Comp analysis
Core idea and suitable matchups.
The composition centers around Mech: Prime 3 for core tankiness, paired with Oracle 3 for team-wide mana regeneration, and Psionic Operative 2 for equipment bonuses. The dual core of Aurelion Sol and Yi provides maximum burst and sustained damage, while Tahm Kench serves as the main tank to absorb damage. In positioning, front-line tanks and warriors hold the line, while back-line carries spread out to avoid concentrated AOE. Overall, it balances offense and defense with precisely matched synergies.

Game plan
Tempo, rolling, leveling and transition notes.
Equipment AllocationCore carry Aurelion Sol: Archangel's Staff (stacks AP every 5 seconds), Jeweled Gauntlet (skill crits), Blue Buff (increases mana regen and AP).
Secondary carry Yi: Infinity Edge (crit damage increase), Titan's Resolve (stacking damage and crowd control immunity).
Main tank Tahm Kench: Warmog's Armor (massive HP), Bramble Vest (armor and counterattack), Dragon's Claw (MR and heal). Remaining heroes receive no items.StrengthsMech: Prime 3 provides significant AD/AP bonuses and transform tankiness; Oracle 3 gives team-wide mana regen for faster skill cycles; Berserker 2 offers lifesteal and attack damage, combined with Psionic Operative equipment enhancement for stable mid-to-late game power. Most heroes are 4-cost, ensuring solid quality.WeaknessesRelies on 2-star high-cost cards, putting pressure on early game economy; lacks grievous wounds and area control, struggling against high-heal or tightly packed compositions; Yi as a melee carry has a mediocre survival environment and needs protection.Early Transition StrategyUse 2 Brawler + 2 Berserker or 2 Oracle early, with low-cost units like Illaoi or Leona. Prioritize holding Tahm Kench, Urgot, and Viktor. Take Rod and Tear for Aurelion Sol, Belt and Chain Vest for Tahm Kench. Focus on preserving HP.Mid-Game ExecutionRoll for core pieces after leveling to 7 at 4-1, prioritize 2-star Aurelion Sol, Tahm Kench, and Yi, then level to 8 to complete synergies. If contested, go to 9 to add Bard or Sona for a higher ceiling. Mid-game, Mordekaiser can replace Zoe temporarily, then swap back later.ReplacementsIf Urgot is unavailable, substitute Cho'Gath for the Brawler slot; Zoe can be replaced by Bard to increase Oracle to 4 (adjust positioning accordingly); Yi can be swapped for Riven, though this will affect synergies.
