If there is a Palladium Dragon, then I would estimate that the combo would be Metal/Lightning. The reason behind this is that the other pair of Treasure Dragons (Gold and Silver) required Fire and Cold, respectively. As those two elements are opposites, it would not be too much to assume that the same holds true for this pair, as well.
