FE Heroes - Battling Clarisee: Infernal
This strategy doesn't require much in the way of uncommon tools. Black Knight and Brave Lyn are units many people should have for free. I used Reinhardt for dealing with the sword-wielding enemies and Elise for healing but these can be replaced with any powerful blue cavalry (preferably mages) and any healer respectively.
For skills, the absolute essential ones are Pivot on Black Knight (found on various characters, Marth being one of them), Draw Back on Brave Lyn (I know Nino has this and she's fairly common) and your blue cavalry unit, Goad Cavalry on your blue cavalry unit, and Moonbow on your blue Cavalry unit. Wings of Mercy 3 is also required on Black Knight but he has this by default.
