hmm all creatures? maybe a bit OP because of all creatures? what about 1? its basically like raising he hp of all your creatures can be deadly if your lava golem's hp goes over atk or is equal
You forgot about Angel's ability didn't you?
Healing all creatures 4 as a +7 cost skill sounds reasonable if not UP.
archangel heals only one creature(+5) and costs the same while angel costs 4 light and heals one for 3 or 4 so its probably ok(im not to good at this)
Guardian Angel has 1atk, 6hp and
:heal target creature 5 for a casting cost of 3
Life Adept has 0atk, 3hp,
:heal all creatures 3 and Adrenaline (with 0 atk) for a casting cost of 5
Less attack, Significantly less hp, Higher cost but gets a mass heal and an almost useless adrenaline.

Does Mend heal the enemy creatures? It is worded so that is a possible interpretation.
