"Gold Sarcophagus" with "Necroface" gives you 6 cards to be banish, including "Necroface" for 2 turns. You can also use "Soul Release" (if "Necroface" is in your graveyard it will also work), "Destiny HERO - Malicious", "Dark Nephthys", "Mezuki" and "Plaguespreader Zombie" to easily banish more cards. Using "Necroface" in your Graveyard with the effect of "Strike Ninja" guarantees the use of "Chaos End" since it would require 2 DARK monsters to banish and "Necroface" would remove 5 cards from the top of both player's decks, plus you do not have to worry about losing "Strike Ninja" because it banishes itself for that turn.
Also you this card in combination with "Inferno Tempest" and "Return from the Different Dimension"". Inferno Tempest will banish every monster in your deck and graveyard, so when you use Chaos End the field is wide open. Then use "RFTDD" to bring your strongest monsters into play. This is a potential OTK.
This card can be used in a deck based on "Agent" monsters with "Master Hyperion" as they can amass a sizable amount of their monsters in the banished zone.
This card when paired with "Soul Release" in a Generation Fish deck can cause devastation to your opponent.
Special Summon "Rainbow Dark Dragon" by banishing 7 DARK monsters from your Graveyard, then activate "Interdimensional Matter Transporter" to prevent "Rainbow Dark Dragon" from being drestroyed, then activate "Chaos End". If your opponent have no Spell/Trap cards or nothing that detain Rainbow Dark Dragon's attack, you may deal a 4000 (or more) direct damage in the next turn.
