Takumi GHB- No Lyns needed

This team focuses on using minor skill inheirtance with pretty decent units. Legendary Ike and Ephraim make this map a joke, and its easy with a good dancer.
I will attach a video showing off the strategy later, but all you need to do is buff ike with hone/defresistance, and run him down the right side. An archer, in my case takumi, just needs a brave bow (not plus) and blue tome breaker1. After sending ike one way and ephraim the other, the map will sort it self out, and you will easily complete it.

Remember, the archer/dancer are interchangeable!
