Analytic
Regenerator
Contrary
Bulletproof
I feel Bulletproof is too specific. Contrary only helps against certain mons as well. Regenerator is quite hampered by SR weakness, thus Latias would be good for CAP still. Finally, Analytic works well against the entire threat list: if the mon CAP tries to check switches, the replacement takes more damage, and may be burned by a STAB of choice. I think of this slate, Analytic serves our purpose best.
