SD breloom, is still without a doubt a threat. The only thing to do is try and take a +1 seed bomb with gyarados and roar it away, because it OHKOs rotom. But that's just one uncommon threat, and most people will just use the spore puncher, which is handled well with rotom/gyarados. Lucario isn't doing much to this team with gyarados and tyranitar alive. EDIT: @LiverpoolFC I know gyarados survives to roar it away but that's it really. It sets up easily with spore and gyara can't roar it more than once. Breloom also completely walls gyara.
