Alright. I shall now attempt to fix your Official Card Grammar. Your grammar is not horrible, however, and it brings to mind older and nostalgic cards.

[b]The Devil Himself[/b]

[i]When this card is Summoned; pay 1000 Life Points and increase the ATK of all DARK monsters by 300. This card cannot be targeted by card effects. While this card is face-up on the field; the DEF of all LIGHT monsters becomes 0.[/i]

Clarifications that are required:
Are LIGHT monsters already on the field affected only, or are LIGHT monsters Summoned afterward included too?
What happens if you cannot pay 1000 Life Points? Do you loose the duel?


[b]Demon Queen[/b]
"Demon" is not a type. Use "Fiend" instead.

[i]When this card is Summoned; decrease this card's ATK by 200 for each LIGHT monster face-up on the field; if "The Devil Himself" is face-up on the field; increase this card's ATK by 1000. If this monster is destroyed by battle; banish it.[/i]


[b]Giant Demon[/b]
"Demon", again, is not a type.

[i]This card can attack twice per turn; if it does, this card's ATK is halved after it has attacked once and this card's ATK reverts to its former value once the Battle Phase is over; no other monsters you control can attack during this turn.[/i]


[b]Demonic Lava Mountain[/b]

[i]FLIP: Search your Deck for "Shield and Sword" and add it to your hand. As long as this card is face-up on the field in defence position; increase the ATK of all Fiend-type monsters on the field by 300 during your Standby Phase.[/i]


[b]Demon Horde[/b]

[i]This card can only be activated when there are no monsters or Spell Cards on your field. Pay 3000 Life Points; Special Summon 5 Level 4 Fiend-type or DARK monsters in face-up attack position.[/i]

Clarifications needed:
Where do you Special Summon from? Your hand, graveyard, or deck?


[b]666[/b]

[i]Roll a six-sided dice. Each time you roll a 6; add 1 "666" Counter (Max. 3) to this card. If you roll a number other than 6; destroy this card; if it has 2 "666" Counters while that happens; pay 2000 Life Points also. Activate the following effects according to the number of "666" Counters on this card.[/i]
[i]*1 "666" Counter: You gain 1000 Life Points.[/i]
[i]*2 "666" Counters: Draw 3 cards.[/i]
[i]*3 "666" Counters: Destroy this card; Special Summon "The Devil Himself".[/i]

Clarifications needed:
Once again, where do you Special Summon from?

Thanks for the feedback.

Beside of what Scrooge pointed, there are other minor things you could change:

* The Devil Himself isn't a Normal Card. It has an effect, so it must be an Effect Card.

* Balance the ATK / DEF of each card. The Devil Himself has a great effect and don't need a 5000 ATK stats. Same goes for the rest of the cards.

And just a tip: You could decrease Giant Demon ATK to 2000 and it's level to 4. It would still have a decent ATK and no tribute to mess up with the opponent
