I found Tornadus to be less useful in the past,
against Plasma Box it is pretty much useless, because Thundurus ruins your day,
its only really consistent against Landorus, but indlucing Eviolite pretty much serves the same purpose.
I also tested 2 Keldeo 2 Float Stone with 1 Switch and 1 Scramble Switch and found it to be incredibly consistent,
with only 4 Switches i just cant deal with the 4 Lasers 4 Catcher everything plays, but once Keldeo Stone is set up, you never have to worry about sleep flips or poison.
