Barricade

At the start of your turn, put a random Attack from your Discard Pile into your Hand and Upgrade it.

Skills cost 0. Whenever you play a Skill, Exhaust it.

At the start of your turn, lose 1 HP and gain 7 Block.

Vulnerable enemies take an additional 25% damage.

Exhaust cards deliberately to turn block, draw, and payoff attacks into a full engine.

Convert permanent Block into offense by keeping it between turns with Barricade and cashing it out through Body Slam.
