Assists and Buffs for my next arena team

I'm making a team of Ephraim, Hector, Celica, and Inigo (yes it is CYL2 themed). Inigo obviously has Dance, while Celica has Reciprocal Aid and Hector has Swap, and I know the ideal Ephraim assist is a rally, but having only one unit with a movement assist (and that unit being armored) I think may frustrate me. I have Draw Back taught to him, so should I go with that or keep the rally? And if I don't keep the rally, should I have a fortify on Inigo? I was also thinking Breath of Life could synergize with Ragnarok and refined Siegmund. Basically I'm indecisive.
