Ditto (SKR 51). Ditto SKR makes all basic energy to rainbow for all pokemon and not just itself including opponent's pokemon. This does not apply to special energy. It also triggers combuskens poke body when attaching an energy to a different pokemon. I am very confident that this is a recent issue caused by some recent change and that it worked fine previously and this issue was likely caused by some somewhat recent change to the programming.
