Eternatus is a nice partner for Pheromosa because it harasses Pheromosa's most common answers in Ho-oh and Toxapex and can take on many Ate Extreme Speed users like Entei, Arcanine, Regieleki, and Dragonite if it has mega'd. On the flip side, Pheromosa does an excellent job forcing out Mews, Blissey, Excadrill, and Kyurem that can all force out Eternatus and prevent it from snowballing through teams with Metronome. The spread is EV'd to live two Altarianite Entei Extreme Speeds even after a burn and the speed is to outpace Salamencite Landorus-Therian so Eternatus is able to take it out with a bit of prior chip or if it gets a few turns of Metronome Dragon Pulse rolling on another target. Metronome is such a strong item on Eternatus in Mix and Mega because it is able to freely come in on so many defensive Mons and not only harass them with Pressure and fish for a poison with Sludge Bomb or a burn with Flamethrower, it is able to do both of those things while continuously strengthening its moves from a very high base special attack stat. Although Metronome's stacking starts slow, it snowballs faster than you would expect and transforms Eternatus from just a bulky Pressure tank to a bulky Pressure tank that is also capable of leveling entire teams if you don't have something to stop it quick.
