Fractal + Nova + this ... and pick a shard of choice...
For that matter, creatures with
cost tend to be difficult to balance in general...
...I shudder to think what this thing would do if used with shards of Void and Gratitude... or even the now nerfed shard of focus.
Right now, this card will give too much power to rainbow and quanta splash decks.
As a permanent or spell, I could get behind this, but its too easy to abuse as a creature.
If you're set on keeping it a creature, then it might work ok with a fused cost (e.g. cost can only be payed with quanta of a single element)... at least then the fractal combo would take work to pull off.
