Ok. Since Infernape is super weak to waters and psycics, Ferrrothorn can be used.
Now we have 2 members.
And a water type should work welll. Starmie/Suicune should do.

4 members.
For the 5th member try Thundurus/Virizion Virizion should work better since it has very good Sp.defence.
And the final member Latios.
