Kyogre is just too strong :/ Arceus normal can setup sweep you easily if unprepared Zekrom is a powerful scarfer, and one of the few pokemon who can scare out Kyogre and Lugia. Mega Gengar defeats any staller no problem. MM2Y Hits like a Truck without boosts, and psystrike gives it a form of mix attacking. Low defense means easily priority killed though. Lugia is known as the wall of china for a reason.. Xerneas is another powerful setup sweeper who can take out an entire team if you lack someone to resist its attacks, or lack a banded scizor.
