Element: Life or Death or no Element at all
Type: Permanent
Name: Life or Death
Concept: All creatures on your side of the field gain +2/+2. All enemy creatures lose -2/-2. If a creature is killed by this card and this card is destroyed then the card will appear as the first card in your deck. (or the card never comes back)
All I need is a picture. I was thinking of a SunFlower with Half Alive and Half dead with the alive part bright and the dead part dark. Or maybe a Mask with Half a Smile and Half a Frown with it being bright and dark or maybe Half Sun half Moon or half the card shows a sun that is rised and a card that is showing nightfall.
Reminds me of a similar card from MTG. As a permanent it's very strong - Eclipse in comparison only buffs two type of elemental creatures, this is worth about 4 times as much as a result(x2 for all elements, x2 for weakening enemy creatures along with strengthing yours).
I would suggest spliting up the three effects in this card - field buff, field weaken, or copying dead cards.
Field Buff would have to be creative in some way, try to give to a certain class of creatures that would really need a buff.
Field Weaken might be good as a permanent that gives all enemy creatures of the opponent's mark -1 |-1.
The copying dead cards idea could be changed so that whenever a creature dies, it goes to your hand or something similar.
