Dialga doesn't hit hard enough without attack investment, and can't tank hits at all without defense investment (and can't function as a proper wall even with investment). It wants dual stabs + fire/earth coverage, and then phazing/twave/stealth rock, but it can't run them all.Why is Dialga not considered very viable, either version of it really, and why is Origin slightly better than the OG?
More so I thought it'd be more useful given its a Dragon that on paper doesn't care about opposing Dragons or Fairies.
As for Dialga-O, it helps with dialga's issues slightly since you get extra damage on STABs and +20 SpD, but you lose out on being able to use leftovers to actually have some longevity.
