More interested in the card gimmick myself. I want to see shuffle and draw mechanic. Something like having 6 carded skills and pressing medium cooldown shuffle skill gives you access to 3 random skills from the deck. You can use only those 3 until you can shuffle for another 3 random draws. Then you have another shorter skill that throws one card back into the globe and draw another card. For some degree of stability you can use another skill that locks down a card to prevent it from taken away on the next shuffle or redraw.

Otherwise i dont really care what it does as a healer cause i aint healing!
