I agree, the SW king is good, but I think that the BET one is also worthy of play. I'm gonna try both... Especially since the king doesn't have to be active for the Power to work, it could be a cool Bench sitter while King SW attacks.
still think kazam 4 could work. you could play nidoqueen with some of the other psychic SP's (don't remember any from the new sets..) weavile could work getting zam out.
