Adding a gavel would be optimal in there, 7 dmg for 2 quanta due to the gravity mark.
The one issue with this is that in the event you don't receive a surplus of Supernovae (say 1-2 in this case), this has the potential to disrupt the quanta balance of the other elements. For instance, you use the 2 Supernovae, play Gavel. Gavel drains you of 1

and 1

. Next turn you draw Abyss Crawler. Bummer :/
