Monsters: Most of the monsters in the deck float, and by being light or dark can allow quick access to "Black Luster Soldier - Envoy of the Beginning" or "Chaos Sorcerer". Cards such as "Old Vindictive Magician" and "Exiled Force" provide ways to out opponent's challenging monsters. With the power of traps, "Jinzo" both neutralises trap decks and acts as a 2400 beater.
Spells: Many spells are here for consistency, such as "Reinforcement of the Army", and to grab cards that can work in any situation. "Heavy Storm" and "Giant Trunade" act as backrow removal, and allow easy damage with the Chaos monsters. "Snatch Steal" and "Brain Control" can utilise the most powerful monsters the opponent may summon and use them against them.
Traps: These traps are all very high impact on the opponent's field, and result in huge gains in card advantage and easy damage for OTKs.
Side Deck: "Skill Drain", "Spell Canceller" and "Royal Decree" are useful against monster, spell and trap heavy decks respectively. Cards such as "Injection Fairy Lily" and "Creature Swap" help for dealing a lot of damage.
Weaknesses: Stall decks that inflict lots of burn damage (sometimes difficult to out their protection in the form of "Swords of Revealing Light" or "Level Limit - Area B")
