Battery: Cauldon Cape is a bit weird because the cards in your hand never get played while charged. Doing something to fix that might be an idea (for example, having her continue to be charged next turn, or allow cards from your hand to end up face down).
Also, the face down cards should be revealed before you play them.
Also also, static charge should maybe reword to be triggered whenever Battery discharges.
