This looks great, thanks! I got to diamond in the last season playing this deck. I found that Draconic Intervention was very good, and I ended up running 2x Intervention, 1x Storm's Wrath, and 1x Shadow's Verdict.
I also found that I almost always wanted Koma over Terror of Mount Velus, so I ended up with 4x Koma. But I keep wondering if having 1 copy of another non-legendary creature would be worth it, as I kept being in the situation of having one fattie on the board, casting or reanimating Burning-Rune Demon, and not being able to get another creature with it because I already have one on the board and both Koma and Velomachus are legendary.
