E6 team and relics

I have e6s1 saber and e0s1 huohuo

I am planning on getting e1s1 gil

For my third slot can be

E2s5 robin

RMC

E0s0 mblade

E2s1 or s5 ddd tribbie

I am assuming since I am e6 saber rmc would be better here to give her more turns? Then I would run atk boots and not speed?

I am gonna farm new planar and use scholar, I dont have any eagle pieces and its not efficient to farm, probably the same on gil as well. However is eagle just way better here?

Ive read alot of posts and the pinned thread but cant come to a definitive conclusion.
