Mana acceleration, card draw, countermagic, and a threat

Other than that, the Extra Deck is filled with a variety of options to go into in certain situations: "Number 39: Utopia Beyond" supports the beatdown strategy by lowering the opposing monster line-up to zero attack, "Constellar Ptolemy M7" bounces monsters you can not destroy, "Photon Strike Bounzer" is a potential turn one play which can block opposing monster effects, "Number 6: Chronomaly Atlantis" is just a beatstick, "Jinzo - Layered" is a "Crackdown" on legs and therefore steals opposing monsters/defenses and "Fairy Knight Ingunar" bounces the entire field except himself
Pokmon cards are back in vogue
If you constantly lose to a Pikachu ex deck, include a couple of cards like Snorlax or Chansey in your deck to soak up the damage while you stack energy on your heavy hitters
