Legends of Runeterra: Thresh and Aurelion Sol Deck Guide

To pull off the Thresh and Aurelion Sol deck strategy in Legends of Runeterra, your goal is to level up Thresh so he can pull Aurelion Sol directly from your deck onto the field. This bypasses Aurelion Sol's heavy mana cost, allowing you to establish a massive late-game threat during the mid-game.

Core Synergy Mechanics

The combo relies on using Thresh as an accelerator for Aurelion Sol:

• Level-Up Condition: Thresh must witness six units die (friendly or enemy) while he is on the board to level up.
• Summon Effect: Once leveled up, the first time Thresh attacks, he automatically pulls another champion—specifically Aurelion Sol—from your deck straight into combat.
• Resource Advantage: You avoid paying Aurelion Sol's high mana cost while immediately gaining his board presence and Celestial card generation.

Playstyle Strategy and Board Management

1. Feeding Thresh's Level-Up

• Aim to drop Thresh onto the board by turn four or five.
• Run low-cost, disposable units or cards that create chump blockers to trade efficiently.
• Protect Thresh at all costs. Do not use him to block high-damage attacks unless it is necessary to prevent lethal damage. Losing Thresh forces you to hard-cast your high-cost cards, drastically slowing down your momentum.

2. Capitalizing on Aurelion Sol

• Once Aurelion Sol enters play, focus on generating and picking low-cost Celestial cards to clear enemy blockers or protect your Nexus.
• Prioritize survival and utility over aggressive overextension until your board control is fully established.

Mulligan Priorities and Counters

Mulligan Phase

• Keep: Low-cost defensive units, early removal spells, and Thresh.
• Replace: Aurelion Sol. You want him to remain in your deck so Thresh can pull him out directly.

Counterplay and Failure Points

• Hard Removal: Spells like Vengeance or Ruination can remove Thresh before he attacks or destroy Aurelion Sol after he arrives. Keep defensive spell mana reserved to react to enemy removal attempts.
• Aggro Burn Decks: Fast-paced aggressive decks can defeat you before turn six. Against aggressive matchups, prioritize trading units and preserving your Nexus health over rushing Thresh's level-up sequence.
