A-Slot for Elincia?

Can't go wrong with LaD/desperation. Swift sparrow works just as well if you have the fodder and want to keep her bulk. However, with +spd her innate death blow would work well too since she'll have 37 speed with her sword equipped which is enough to quad a ton of units after a speed buff

I prefer Firesweep+Swift Sparrow+Hit and Run. People say that Life and Death is better since you are not gonna get damaged but there are times when mages are able to attack her even when using hit and run but with her 27?26? res, unless they are blue mage, Elincia can survive hits. But if going flier team I say stick with L&D since there is reposition on your team.

If you are going Amiti, do not go L&D... A lot I mean a lot if times, you can't even win against green units in arena high tiers because you will proc their special and they will kill you with you horrible def stat even though you are initiating. Try to get Swift Sparrow if going Amiti quad or double build.
