There are many ways to make you get the edge after Norleras (or "Phantom of Chaos") has nuked the field. If you have "Plaguespreader Zombie" in your graveyard, you can use his cost to put "The Dark Creator" on top of your deck. Then nuke the field, draw "The Dark Creator" and special summon him immediately. Then use his effect to revive a strong dark monster like "Dark Horus" or "Archfiend Empress" and attack your opponent directly. Your opponent will be stuck topdecking to counter your assaults. If you summon "Red-Eyes Darkness Metal Dragon" and use his effect to summon "Dark Horus", this deals 8100 damage - an OTK.
You can chain "Interdimensional Matter Transporter" to the effect of "Sky Scourge Norleras" so that he gets to attack your opponent during your next turn while they have no cards, thus damaging them severely.
Though, you should enjoy the card you've drawn with the effect of "Sky Scourge Norleras" to get an extra advantage.
This card works well for a "Hopeless Dragon", "One Turn Kill" Deck. You can copy Norleras' effect using "Phantom of Chaos". If your next card is "Dark Creator" you can special summon him and then summon a "Red-Eyes Darkness Metal Dragon" from your grave and then use his effect to summon another powerful Dragon. Your opponent would have nothing to protect himself since all cards on the field and in his hand are thrown to the grave.
Before you activate "Norleras" effect, activate "Gold Sarcophagus". The card will be unaffected by "Norleras" since it's in your banish zone, and will return to your hand, giving you further advantage over your opponent. You can also use "Evil HERO Infernal Gainer" in a similar way. You can also send "Dark Nephthys" to the graveyard with his own effect. It will survive "Norleras" nuke and special summon itself next turn.
Be careful when using this card against "Infernity" decks, as the hand-wipe effect can actually help your opponent, especially if they draw "Infernity Archfiend" during their next draw.
Use this card's effect while you have 1 or more "Lightserpent" in your hand. Their effects will special summon themselves, and have free direct attacks for 1200 damage each.
If you use "Painful Choice" to pick up "Norleras" and target 3 Fiends and 1 Fairy to Summon him and use "Dimension Fusion" to Summon the banished monsters for "Norleras'" Summon you may bring down the opponent easily after using his effect. But you should draw "Dimension Fusion" after using "Norleras'" effect.
