Basic deck:
Strike x4
Defend x4
Mockingbird x1: 1 (0) Energy | Attack | If the enemy intends to attack, copy its attack.
Confound x1: 0 Energy | Skill | [Double the enemy's Weak. Apply 1 Weak.] (Apply 1 Weak. Double the enemy's Weak.)

New debuff: Leech
Leech deals X damage to the target at the end of each turn and turns half the damage dealt into Block for the player, where X is the stacks of Leech. Leech bypasses opposing Block. Leech wears off two turns after being applied. Because Leech does not gradually decrease like Poison and it also provides the player with Block, most Leech sources apply less Leech than equivalent Poison sources.
