Balancing Booster Sets #5 - Labyrinth of Nightmare

[Baneful]

LON is a step back from PSV in terms of card quality, but nonetheless, a number of the cards from the set can be quite good (and splashable) with the right buffs.  I particularly made Masks a viable deck and Destiny Board not terrible.

1. Gemini Elf - Battle damage this card inflicts is halved.  (That way she doesn't make every other beater obsolete)
2. The Masked Beast - When it is successfully Ritual Summoned, add up to 3 "Mask" cards from your deck and/or graveyard to your hand.
3. Revival Jam - Its effect applies if destroyed by a card effect, as well.  You only have to pay 700 LP instead of 1000.
4. Melchid the Four-Face Beast - When this card is Normal Summoned, reveal the top 4 cards from your deck.  Add up to 2 "Mask" cards from them to your hand, and shuffle the remaining cards into the deck.
5. Nuvia the Wicked - No summoning restrictions.
6. Chosen One - The remaining cards are returned to your hand (whether you choose correctly or not)
7. Mask of Weakness - The ATK loss is 1000 instead of 700.
8. Mask of Dispel - The effects of the card you select are negated.
9. Mask of the Accursed - The monster's effects are negated and it loses 1000 ATK.
10. Mask of Brutality - When this card is destroyed, add 1 "Mask" card from your deck to your hand.
11. Return of the Doomed - No discard cost.
12. Lightning Blade - ATK boost is 1600 instead of 800.
13. Jam Breeding Machine - No summoning restrictions.  Tokens can be summoned in Defense Position.
14. Infinite Cards - Draw 1 card during the End Phase of the turn you activate this card.
15. Card of Safe Return - Can only activate once per turn.  Can only control 1 "Card of Safe Return"
16. Fire Princess - Once per turn, you can draw 1 card if this card inflicts battle damage.
17. Spirit of the Breeze - Once per turn, you can draw 1 card if this card increases your life points..
18. Marie the Fallen One - Is a LV4 monster instead of a LV5 monster.
19. Dark Necrofear - Only requires 2 Fiend-type monsters to banish instead of 3.
20. Tornado Bird - Can return any 2 cards on the field (excluding itself)
