Pyre

Pyre is a 3-cost Rare Attack card for the Ironclad that deals 25 damage to ALL enemies and Exhausts itself. The massive AoE damage at the cost of a high energy investment and self-Exhaust makes it a powerful one-time board clear.

Pyre's Exhaust triggers Dark Embrace for draw and Feel No Pain for Block, adding utility to the damage. Inflame and Demon Form boost the AoE damage significantly. Offering provides the energy needed to play Pyre alongside other cards. Forgotten Ritual gains energy from the Exhaust trigger, partially refunding Pyre's cost. In the Exhaust pile, Pyre contributes to Ashen Strike's scaling. Howl from Beyond can provide recurring AoE alongside Pyre's one-time burst.

Pyre is one of the Ironclad's most devastating AoE options. Pick it when your deck has energy generation to support the 3-cost. Against Test Subject #C10, 25 AoE damage clears summons while dealing massive boss damage. Against Soul Fysh, the burst AoE can end the fight before things get dangerous. The Exhaust means one use per combat, so time it for maximum impact. The Ironclad's energy tools like Offering and Bloodletting make Pyre more playable than its cost suggests.
