Interesting. Thematic.
Unupped is 4 (or occasionally more) damage per
but no net hp swing (usually).
Acts as a defense/counterdefense against Max HP changing effects (SoV/SoD/Stoneskin).
Use in a rush: It would reduce the hp target for both players making the quicker clock (the rush deck) able to finish the game sooner evading the slower defense. However it is expensive for this use.
Use in a stall: Combined with SoS it would provide healing for you while damaging the opponent. It also reduces the threshold of opponent offense needed to make SoS worthwhile. Combining with SoD is risky and probably not worth it. I am unsure if it is worth the cost for this use.
Upped is 4 (usually more [SoD/Stoneskin]) healing per turn but heals the opponent 4 (possibly less [SoV])
Acts as a defense against damage.
Use in a stall: Healing. The maximum it would heal would be 20hp. Usually it would heal less. 1 quanta is worth about 5healing but repeated uses are more valuable and the casting cost investment needs to be returned. I would assume it is balanced but I am unsure due to the complexity of the deck type involved.
