The new Greninja ex is really good as not just does it a a low cost set up attack but also has a better snipe that can kill biberal and you could pair it with boomerang but you could use it with baxscalaber to set up quickly and hit 120 to 2 every turn and you already have the candy package
What you have forgotten is that iron thorns 1 shots lugia and is played in future box which plays 4 switch and still allows your abilities and you can just search it out and play it down and this turn on one with pokemon headquarters and unfair stamp would be crazy.
