Molten Fist

Molten Fist is a 1-cost Common Attack card for the Ironclad that deals 10 damage, doubles the Vulnerable on the target, and then Exhausts itself. The Vulnerable doubling makes it a powerful setup card for Vulnerable-based strategies, while the self-Exhaust triggers all Exhaust synergies.

Molten Fist doubles Vulnerable applied by Bash, Brand, or Tremble, making it a devastating amplifier in Vulnerable decks. The self-Exhaust triggers Dark Embrace, Feel No Pain, and fuels Ashen Strike. It satisfies the Exhaust-this-turn condition for Cascade, Evil Eye, and Forgotten Ritual. Follow with Stampede or Bully to capitalize on the doubled Vulnerable stacks. Dismantle hits twice on Vulnerable targets for massive damage.

Molten Fist bridges the Ironclad's Vulnerable and Exhaust archetypes. Pick it when you have strong Vulnerable application already in place. Against single-target bosses like Ceremonial Beast, doubling Vulnerable before unleashing heavy Attacks is devastating. The self-Exhaust means you only get one use per combat, so time it for maximum impact. It is an excellent Common card that supports multiple Ironclad strategies simultaneously.
