wow, thanks this something I can work off of,I can't use the keldeo though its not kalos born but I can definitly use this thanks alot

Ah, my bad, I knew Terrakion, Virizion and Cobalion were available in ORAS so I just assumed Keldeo was as well, Greninja is a Pokemon that can be used in place of Keldeo to reliably deal with Ferrothorn because of Low Kick/Hidden Power Fire.

For my Keldeo, I like it more like this because M-Metagross doesn't need the Icy Wind.
Keldeo @ Leftovers
Ability: Justified

Timid Nature
- Substitute

More defensive with Substitute+Calm Mind usually works and Scald STAB with chance of burn and Secret Sword is primary move like Psyshock but with STAB.
