Did you have to teach your grandma how to find eggs? I know it's HP, not Life quanta, or "green mana" how those FLOCKING MTGIANS call it.
And, I say, something along 7 or 10 is a more viable cost. But with no quantacost.
So, maybe the new cads of this...
Nova: Spell (Free, Entropy flavour)
Pay 7 HP to get 1 quantum of each element + 10 random quanta.
Supernova: Spell (Free, Entropy flavour)
Pay 12 HP to get 2 quanta of each element + 10 random quanta.
