Venusaur covers Xerneas and Kyogre, but you need to be careful about letting it get weakened for +2 moonblast (does like 45% max). Power whip can go over grass knot because otherwise calm mind ogre is a struggle. The 19 speed ivs with sassy on venu allows you to underspeed magearna and get off a leech seed. Skarm checks physical necro dusk mane and ultra necro as well as mega mence, but watch out for taunt. Tyranitar deals with yveltal and can check ho-oh in a pinch, but don't rely on not getting burnt. The aguav helps a lot when your opponent thinks they can weaken you enough with yveltal. Yveltal eats stall for breakfast and can annoy support arceus versions if you let metronome oblivion wing rack up. Arceus ground checks groudon and zygarde, while necro dusk mane is a back up zern check and win con.
