Well she has Lucario, Machoke, and Meditite I believe. And since they're fighting, and Meditite is Psychic as well, they're good against Normal, Rock, Ice, Steel, and in Meditite's case, IF it knows a Psychic type, it's good against Poison, and Fighting. To take her out as quickly as possible, I'd have a Staravia with Aerial Ace, and maybe Endeavour, and Quick Attack. And a strong/Fast Fire type for Lucario.

Giratina's weaknesses are Ice, Ghost, Dragon and Dark.
Arceus has the best overall stats. Spiritomb has no weaknesses. It really depends on who you're fighting.
It is always a good idea to have a team that has various different types, strengths and weaknesses. This way you will be able to anticipate for any Pokemon that comes your way and you will be able to choose the Pokemon that has the tactical advantage in your team.
