Notes & Combos
Abyss Dragon can search Deep-Eyes for protection turn 1, and the burn makes it easier to finish games by just swinging over your opponent's monsters even if they can't be destroyed.
Solid Dragon is useful for negating monsters like Kluger and Roach. Be aware that a negated Ultimate Nightmare will still burn you and pop your monster after you destroy it by battle.
You can banish backrow with Dragon Spirit of White, but sometimes it's better to just swarm the board with 4000-atk beaters since each backrow card can generally only stop one monster.
If you can summon Chaos MAX, that can be an auto-win against certain decks unless they have Ice Dragon's Prison.
The deck can play through backrow, but negates like Roach, Clear Wing, and Crystal Wing are a big problem, so Chalice is really helpful.
I never needed Neo Ultimate, Michael, or Inti. I might honestly just play 3 Spirit, 3 Azure, and 2 Twin Burst.
