Ok, so because it has to be trio, are shards allowed? do shards count as an "element" because they are "other"?
IE: 6x SoG's and a duo deck is not allowed, yes?
IE2: 4x shards, 6 of one element, 9 of another, and 11 of a third element is allowed, yes?
Hopefully I stated my question clearly and that the answer isn't hidden somewhere I didn't find xD
