Cascade

Cascade is a 2-cost Rare Attack card for the Ironclad that deals 15 damage, and if you have Exhausted any card this turn, it deals 15 damage again for a total of 30. This conditional double-hit makes it one of the highest-damage cards available when the condition is met.

Cascade requires an Exhaust trigger on the same turn, making it natural to pair with Burning Pact, Stoke, or True Grit as setup. Molten Fist Exhausts itself, providing both Vulnerable application and the Exhaust trigger Cascade needs. Cinder Exhausts the top of your Draw Pile, another easy trigger. Dark Embrace and Feel No Pain ensure the Exhaust triggers generate additional value alongside Cascade's damage.

Cascade is a powerful finisher for Ironclad Exhaust decks. The 30 total damage for 2 energy is exceptional when the condition is reliably met. Pick it when your deck already has cheap Exhaust triggers you play naturally. Against bosses like Ceremonial Beast, the burst damage from Cascade can end the fight before the boss becomes dangerous. It is unreliable in decks without consistent Exhaust and should be avoided if you cannot guarantee the trigger.
