While Sprocket is designed for assassination, Hellmaw focuses on economic strength. As an economy-based champion, Hellmaw allows The Forged to excel in attrition battles. The ability to recycle cards is incredibly valuable.
The ideal play involves using a low-health unit or structure, attacking with it, and then using Smelt Down to deny the opponent magic while returning the unit to your deck. Additionally, this opens up space for other units to attack, especially ranged units.
Hellmaw is best in slow-paced games, where recycling damaged structures can provide a significant advantage.
