Can be used on turn 6 and onwards. Add 1 "Blue-Eyes Chaos MAX Dragon" to top of your Deck. In addition, add "Chaos Form" to your hand from outside of your Deck if your opponent controls monsters with 3500 or higher DEF. This Skill can only be used once per Duel.
Yes, all duelists at the gate are legendary duelists. It doesn't matter who your opponent is. Just make sure that you use Kaiba (DSOS).
First off this skill is op. Turn 6? Thats nothing. You could run a stall deck and then boom got a 4000 atk monster that does double piercing damage to a defense position monster. Duel links. Stick to regular skills. Power of dark. Peak performance. Destiny draw even. Chaos max dragon is too powerful to just give it a skill that brings it out with such ease. Run a stall deck or dragon spirit of white and you win 80%
