Still, just looking at the combos from that video... I feel like there's a bit to improve on.
Savior is aggressive. Volcanic' is terrible at aggression, as it's either way too uncontrollable and low impact when unworn or far better for a balanced Stamina build if it's awakened. Use Xtreme'/Quick' or another good rubber flat driver on that. Valkyrie's core is also not good on offensive combos, so you'd probably be better off with Belial or Ragnaruk.
The Vanish combo is trying hard for same-spin by using Momentum. If you have a higher LAD driver (Xtend+, Bearing, Zone'+Z, Drift) you'd be better off with that over Momentum, since you'll be able to win against more right spin combos. As it is, any good right spin bey wins against this.
Astral is trying to do the same thing as Vanish, with no hope against right spin beys short of maybe a lucky KO. Bahamut is the only thing even holding it together too. The same thing I said about Vanish applies there too, though I might switch it out for something like Dynamite+F anyways to cover more matchups.
This deck is basically a weak Attack type and two left-spin same-spin stamina types, one which can put out a little aggression. Right spin LAD bodies all three combos easily, and it's common to face. You're not gonna get far unless you can cover that.
