Few things to say:
1. Picture could totally be redone, I apologise. 
2. The card can be a rare card, your choice.
3. If the card is NOT rare, it should cost around 200 Coins.
4. If the card is chosen to be rare, it should sell for 256 Coins.

Finally:
5. The cost of the Card is 12. I understand if you think it is a bit low, so it can ascend upto 15. Your Choice.

Welcome to card ideas and art. :3
First of all, the idea should be posted on this board: http://elementscommunity.org/forum/card-ideas-and-art/
This is because design theory is more so used for non-card ideas, ideas completely not presentable card ideas, and also advice and tips for designing cards in general.

Now we have that out of the way, the card is... Kinda weak, actually.
The reason for this is because, at least to my understanding, damaging cards (like thunderstorm and rain of fire) usually aren't that played, and you rarely see poison from parasite/plague, if ever. So the full heal effect isn't too useful in that regard.

The really interesting effect is buffing the maximum HP of everything, but a plate/heavy armour on all creatures would cost about 6/7, not 12, and the full heal doesn't justify raising it to 12 in most cases.

Post the card on http://elementscommunity.org/forum/card-ideas-and-art/ and reduce the cost to about 7.
Bonus points for making a life card that actually works as a life card. That's... A lot harder than it sounds.

Reminds me of a card I made a while back. It affected every creature on the field though.
