Havoc

Havoc is a 1-cost Common Skill card for the Ironclad that plays the top card of your Draw Pile for free and then Exhausts it. This effectively lets you get one final use out of a card before removing it, or play expensive cards without paying their energy cost.

Havoc is powerful with Headbutt, which lets you place a specific card on top of your Draw Pile to be played by Havoc next turn. Dark Embrace and Feel No Pain trigger from the Exhaust. If Havoc hits an expensive card like Bludgeon or Pyre, you get massive value from the free play. Drum of Battle's top-of-deck Exhaust can be replaced by Havoc's play-then-Exhaust for better value.

Havoc is a high-variance card for the Ironclad that rewards deck manipulation. It is best in smaller, curated decks where you know roughly what is on top. Pick it when you have Headbutt or other top-of-deck manipulation. Against Kin Priest, playing a free card each turn provides the tempo advantage needed. The randomness makes it unreliable in large, unfocused decks. In Exhaust builds, the Exhaust trigger alone can justify its inclusion.
