you know what is a bad game design?
creating "other" cards with abilities open for all the elements for the sole purpose of making mono or duo decks competitive and playable
i suppose you never played MtG.. for example life gaining is the main "ability" of the green element, while direct damage is specific of the red element, you will never have a "uncolor" or red healing spell that is stronger than a similiar green card... because if you want life gaining you have to chose green!
the problem of "Elements" right now is that a single element has not enough cards to allow consistent mono or duo powerful decks...
creating cards with generic quanta to solve this problem (as you suggest) it's a bad solution, because you make every element unpersonal.
in my vision, shard of gratitude should be a
card not "other" type...
everyon splashes 4 SoG in every deck because it's plain useful having a way to heal yourself even in mono fire charge decks.
bottom line: i am personally against novas and supernovas, a single card that gives you 24 quanta and that allows you to play rainbow decks easily should not exist...
that's what a life playing CCGs taught me...
