everything is this team is great apart from two things
switch life orb from reiniclus and give it to darmanitan and shell bell to reiniclus because it works well with recover and reiniclus good hp
the other reason why is that when sheer force and life orb are together you get both of the boosts to move power but no damage to darmanitan from the life orb(this is actually true,its a great strategy
with the blissey this moveset works well
seismic toss/counter(blissey has ok sp attack)psychic softboiled and toxic(while you stall with softboiled they slowly die)
