Okay so here is it:
Running Diamond Dude is solid but he's Dark and his use isn't much well sometimes...
What we're getting are Necloths and Qlips, so we need to have beaters. I prefer playing Neos Alius (LV4/1900) and his bruh Koga that goes above 4k and when you have Shining, it's amazing.
By having them around, you can also do some nice plays with BLS as well.
I don't like Summoner Monk much because he knows to send your useful spells. It doesen't happen very often but it's more about player's taste though.
So by cutting those stuff (D. HERO Cards, perhaps Monk and DAD) you should change this with some backrow cards.

This is my Skelet for upcoming return of HEROes because we have a big change in a next format. As you may see, every part of the deck has to be updated a bit, from Main to side including Extra. It's decent, consistant and fast enough and I belive we shouldn't have big problems with it :D
