Whirlwind

Whirlwind is an X-cost Uncommon Attack card for the Ironclad that deals 5 damage to ALL enemies X times, where X equals your current energy. Spending 3 energy deals 15 damage to all enemies, with each hit benefiting from Strength bonuses for potentially massive total damage.

Whirlwind scales with both energy and Strength. Offering and Bloodletting provide extra energy for more hits. Demon Form and Inflame add Strength to each hit, so 3 hits with 5 Strength deals 30 damage to ALL. Vulnerable from Taunt amplifies every hit across all enemies. Forgotten Ritual and Stoke can generate extra energy the turn you play Whirlwind. Expect a Fight provides energy based on Attacks in hand, fueling a bigger Whirlwind.

Whirlwind is the Ironclad's most scalable AoE card. Pick it when your deck has energy generation and Strength scaling. Against multi-enemy encounters, a high-energy Whirlwind with Strength wipes entire groups. Against Test Subject #C10, it handles summons while damaging the boss. Against Kaiser Crab, the multi-hit nature helps cut through Block. The Ironclad's energy-generation tools make Whirlwind one of the highest-ceiling AoE cards in the game.
