If that strategy hasn't wiped out your opponent's Life Points, defuse "Arcana" back into its Materials using "De-Fusion", then attack using the 3 "Knights".
Cards that can get specific cards in your hand can be good. "Sangan" (Traditional Format only) for monsters, "A Cat of Ill Omen" for Traps, and "Toon Table of Contents" for Deck thinning and a left over Spell Card. Another good card is "Gold Sarcophagus" which can search out any type of card, but it takes a few turns to get the card.
This card works well in Decks with "Jinzo", "Tyrant's Tirade", "Royal Decree", and/or "Trap Stun". By removing your opponent's ability to use Traps, focus on having a hand full of Spells and monsters to negate those effects.
If using "Tyrant's Tirade", use "Skill Drain" to prevent your opponent from using monster effects while still being able to use your own monster effects, allowing yourself to not have to worry about keeping monsters in your hand to protect your monster.
