For T9 I usually go with

1st Beak, Rampart ( I use it here first so it came back in time for 3rd Beak)
2nd Beak Foresight/Conva + Virus,
3rd Beak, Rampart again.
4th Beak (if your team has low DPS, Bulwak for beak, Sentinal for Ascent.

I'm also counting on my healer to cast stone skin and alldo (sch shield lol).
