It is basically the negative version of Steal / Improved Steal. Instead of taking a permanent from your opponent and giving it to yourself, you take one of your own cards and give it to your opponent. The way I am looking at it, it would fall under Darkness (like Steal), and would cost the same as Steal / Improved steal. This could result in an interesting new game play mechanic that we need to watch out for.
Say perhaps, that there is a new shield absorbs all damage taken for one turn and delays its effects for 2 turns. (In two turns it deals the damage to you.) (Oh snap, another card idea, to mull over! That's what we call a two-fer!). You could use Dark Gift / Grim Charity to give the shield to your opponent after they attacked it and let them attack themselves. That is just one example, perhaps it could also have a dual purpose where it could either give a perm or give up to 2 poison damage that is already attached to your health to your opponent.

This has been suggested before by
ScytherLoL in his topic, I was unaware of this fact and just would like also give some credit where credit is due (he actually did some concept art too).
http://elementscommunity.org/forum/index.php/topic,3240 (assassim's topic)
It has been brought to my attention that this has been suggested previously once again by
assassim. Again, sorry for the repeat topic and credit also goes to him. (also provides some concept art).
http://elementscommunity.org/forum/index.php/topic,2214 (Luxus's topic)
Another previous topic where a similar card was suggested on the forums, this time by
Luxus.
http://elementscommunity.org/forum/index.php/topic,4977 (ManOfManySpoons's topic)
This idea seems to have some legs to it, already spawning another branching topic of support cards for this by
ManOfManySpoons.
P.S. If you know of or find another Card Idea thread pertaining to this type of game mechanic or specifically this card idea, it would be great if you post a link of in the responses. I will be happy to create a compendium of sorts for this sort of idea since it seems to be generally well received by the public and it will make it easier for administrators to work with the idea if they decide to do so.
