Barricade

Barricade is a 3-cost Rare Power card for the Ironclad that prevents Block from being removed at the start of your turn for the rest of combat. This transforms Block from a temporary resource into a permanent one, allowing you to accumulate massive Block stacks over multiple turns until you are essentially invulnerable.

Barricade's primary partner is Body Slam, which converts your accumulated Block into damage. Shrug It Off, Flame Barrier, Impervious, and Tank all generate large Block amounts that now persist between turns. Iron Wave provides both Block and damage in one card. Juggernaut deals 5 damage to a random enemy each time you gain Block, turning your defensive engine into a passive damage source. Demon Form provides the Strength scaling that Body Slam needs to deal lethal damage.

Barricade is the cornerstone of the Ironclad's Block archetype. Pick it when your deck has strong Block generation and ideally Body Slam as a win condition. The 3-energy cost is steep but the payoff is enormous. Against Kaiser Crab, Barricade lets you build an impenetrable wall and then slam through with Body Slam. Against Doormaker, the accumulated Block carries between phases. It is one of the Ironclad's most powerful build-around cards but requires commitment to the Block strategy.
