Sorry for the necro, but it seems worth doing so to bring up a relevant point.
With the current changes to shards, this card would likely need to be put into the earth element.
I actually think that this would fit very well in earth though, so that isn't an issue.
Of course, that would end up giving 2 shards to earth.
One very reasonable solution would be to move shard of integrity back to type "Other".
Since SoI essentially chews up other shards from every element I think it fits as an "Other" type card very well.
