I'd just like to point out to all you peeps designing new shards that Zanz specifically said he wanted every shard to be more effective when used with it's element than otherwise. Thus, Shard of Sacrifice keeps your
quanta, and the new Shard of Readiness will have a buff when used on
creatures, etc.
My submission, for example, works more effectively when you have plenty of
creatures in play.
If your intent is to make something Zanz might actually use, you should consider that concept when balancing your mechanic.
