ORAS Team Help

[NailFarukon]

So my friend and I are going to battle at level 100.


His team is:




Blaziken, Breloom, Milotic, Dusknoir, Metagross, and Crobat.


My team is:
Swampert, Gardevoir, Aggron, Salamence, Hydriegon, and Kingdra.




Do I stand a chance with this team? Can I make it work or are amends a must?
What moves/anything do you recommend?


Thanks!
