This needs some clarification.
Do you get a copy of the creature?
Do you copy-and-paste an opponent's creature ability to one of your own?
You neither get a copy nor do you copy-and-paste the ability on your creature. You simply use the ability of the target creature.
The creature still damages you and remains on the opponents field.
Fix the cost. It should say 7 or whatever you want it to be. Also, the cards should be bigger. Use www.imageshack.com
The cost of the card is Entropy, as it states in the element field. I will work on making the image larger.
Edit: I have added the icon next to the cost as you requested and enlarged the image. Thank you.
