Fire Emblem: Gods of the Celestial Realm [OOC]

Consider something like this

Mage moves four north, slams the merc.
Peg moves one north, carries mage, moves two north one east, drops mage west
Archer flees one south four west. Will be safe for a turn.

Next turn, peg delivery service protects archers.
Further actions depend on how the enemies pursue the split party.
Enemies are forced to chokepoint around the corner to bumrush mage+peg. Good spot to pop merc.
If they pursue archer, time bought to haul archer over wall
If they split up... well that would be too much to ask for I guess

I'm in a rush, so doublecheck me Sothesians!
