The plusle almost seems like it would be easy Bring Down bait. With no way for Feraligatr to spread damage, with every basic in G&G having 60HP or above (unless you are using the old ralts), it would be a free prize whenever they wanted it.
i guess you could attach the unown g to it, which would make it immune to bring down, but they could always windstorm that too.
I would be relieved if they used Bring Down on it rather than shut down my powers or fling my gatr to the bench severly wounded, actually. In fact, I would probably drop another one and collect the energy from them knocking out one of my pokemon, and get a revenge KO as a result.
