Hero Build Overview/Explanation

This build is crazy. You will have infinite miracle thanks to Ares's incredible weapon, heavy blade and Eir's new skill. The idea is that you use dark mystletainn to lower the cooldown of miracle and help reducing the cooldown if the special if Ares couldn't get it ready into battle. By the way reposition is just there, you can change it to whatever you prefer. Miracle is the key of the build. Life and death grants more speed to ares to avoid doubles and increase his attack to make heavy blade proc more safely. Mystic boost will ensure that, after battle, ares always has more than 1 hp to make miracle work. In the end, threaten defense is just there as well to help him do more damage, but I don't think it is crucial to the build.

Explanation over, but here are a few interesting notes:
I haven't tested this build yet. In fact I saw it at a Japanese channel and, although I can't speak japanese or anything, some friends and I discovered the build and the guy (who made the video) showed it in action. So you can trust it :D
One more thing. I particularly invested a lot in an Ares that I have (he is +7 now with distant counter and everything from the first build you will find in this page). I also gave him summoner support and, in the end, his offensive stats were better than the Ares of the video, so I will try running this build with distant counter instead. If it works, I will notify you people by editing this post.
One last thing (I swear). The video was posted on YouTube on 15th of December of 2018. I could find it by simply searching "Ares FEH" and videos from the past week.
The thumbnail is Ares and a big DEF and RES with a yellow symbol of the infinite. Anyway, the video won't be hard to find I guess.
