Shard Gratitude is not quite good to be "shard" which is "rare" in that title. It is like just normal card with mark as "other".
When use by life, it is heal by 5. just differ 1 to sanctuary when be used by light. Other than that, sanctuary give more effect, so we can tolerate the 1 heal point to its effect..
In summary, to be good as "shard", SoG should be buff more.
I absolutely agree to idea to heal
creatures 1 point per turn..
