Nino's "Draw Back" evasive movement skill is amazingly fun. If Jaffar is ever added, I'll draw him, too! However, because the commander doesn't move, Linda also doesn't move. I want Biri-BiLinda!
That said, using someone like Selena's "Reposition" is more generally useful, since Draw Back only pulls the glass cannon back one space, but reposition tosses the squishy character back two spaces while leaving the more tanky Selena in front of them as a roadblock.
Nino's draw back can benefit Linda more for the next turn too since Nino gives atk plus buff to adjacent units at the beginning of the turn.
Abilities like reposition do the same thing, though. Honestly, I find the best skills are ones like Gunter's Goad Cavalry (+6 Atk and Spd) combined with characters like Olwen or Eliwood using Ward Cavalry (+4 Def and Res). An all-cavalry force basically gets +4 or +6 to all stats just for sticking together. Combine this with Olwen having reposition, and you can charge up attack power by being near Gunter, send out a fast cavalry attack with a ranged cavalry unit like Cecilia, then reposition the unit back to being near Gunter and out of harm's way.
