A quick suggestion for an edit of morale.
Make it a spell (I think it already is).
1) If your opponent has more hit-points than yourself, all his creatures gain +1/-1
2) If you have more hit points than your opponent, all your creatures gain +1/-1
Reasoning, if your opponent is winning - his creatures think that the end is near and become more reckless, focusing on offense instead of defense. Likewise, if you have more hit points than your opponent, the same thing happens - but this time for your creatures.
Maybe costing about 5 Quanta, definitely of something, not any. Maybe Light. Not sure.
It has to cost a specific element because 6 of these act like two Rain of Fires - for 30 of any quanta, that is cheap. For 30 of a single quanta is about right.
