Even if it can be used to heal your own creatures, is it really worth that cost? Doesn't really look like it. Most creatures are often killed in one turn by CC. This card could heal frozen/delayed/antimattered creatures, but that's probably going to be as useful as it is for your own creatures. If you want to remove buffs or cool mutants from your opponent, RT does that better. I say change the cost so it's 3|2 at least.
