A standard special Shaymin/Celebi seems like a major threat to your team, being able to outpace and 1HKO 4 of your Pokémon, assuming no Calm Mind set up on Suicune. I see this being easily taken care of by a Life Orb Weavile, with an STAB priority move and access to Fake Out, making a wonderful revenge killer. The one objection to the idea would be; WHERE THE HELL WOULD YOU PUT IT? I see that Weavile makes a much better alternative to Flygon with his access to Ice STAB, and incredible base attack. Metagross covers all of his weaknesses sans Fire, which Suicune can easily absorb.
Weavile@Life Orb
Ability: Pressure
Jolly: 4 HP/252 Atk/252 Spd

-Night Slash
-Brick Break/X-Scissor
This seems like it would help control any speedy threats, and is easily protected by the rest of your team.
