Heavy Knight of the Flame, when re-summoned to gain his effect, removes from play any special summoned monster he battles. This is especially good against decks centered around special summoning monsters, like REBD decks and Toons.
Super Rush Headlong allows you to destroy any monster of a certain attribute of your choice with it's effect. Use this while your opponent attacks for both defense and monster removal.
Use spell/trap cards to protect your monsters and maintain control of the field. Enemy Controller and Windstorm of Etaqua changes the battle position of your opponent's monster to cancel their attacks.
