RTA - Sleeper Picks

For the upcoming RTA, who are some of your sleeper picks? Obviously, no one is wanting to give away this info, but it will be found out very quickly anyway.

Personally, I'm interested to see how Yuna will fare (SSS, +10 speed from EE) knowing she has attack and speed up which in theory could be helpful in RTA. I'm also in the process of building ML rin with her steal buffs, as well as Cecilia/Tenebria for AOE provoke/def break.

Any units you think will be sleepers? Obviously the good ones like SSB will be picked about 100% of the time.
