Warcraft: Path of Darkness and Death

[EmilyAnnCoons]

These are Yu-Gi-Oh cards based around my World of Warcraft characters. Tell me what you think and how I can improve it (if it is overpowered, please tell me what I can do to fix it...saying "op" won't tell me how to fix the problem...I am already assuming they are overpowered, I just need someone to help me fix that).

Once per turn, during your Standby Phase, as long as this card remains face-up on the field, you may sacrifice 300 Life Points to activate one of the following effects:
- Deal 300 Life Point damage to your opponent.
- Lower the ATK of one of your opponent's monsters by 300.
- Lower the DEF of one of your opponent's monsters by 300.
- Summon 1 Demon Token (Dark/Fiend/1000/1000) to the field.

During your Standby Phase, as long as this card remains in face-up Attack Position, increase your Life Points by 500. If there is a card with "Ranawen Elendil" in its name on your side of the field, this card cannot be the target of an attack.

This card cannot be Normal Summoned or Set. This card can only be Special Summoned by sending one "Warlock - Ranawen Elendil" from the field to your graveyard. If this card attacks an opponent's monster, that card loses 500 ATK. If that card is destroyed by this card, decrease the ATK of all adjacent monsters by 500.

You should put Once per turn so someone doesn't say I use the direct damage effect for -8100 (or 27 times) to tie the duel
Otherwise, yah nice the rest are balanced effects if used once per turn desent pic and OCG looks good.
8/10

Awesome, I'll edit that when I get up tomorrow. I'm working on the next card in the set as well.
