I'd say "Self-Scramble" on the card test to clarify it is scrambling the owner's quanta.
Card Cost = Attack + HP + Ability Threat + Bonuses
I will do both cards together since they're pretty much identical.
Attack = + 0
HP = + 0
Ability Threat = + 6 (Scramble + 5 , Immaterial + 2, Overload -1)
Bonuses : If upgraded, -1.
Final Cost: 6
| 5
Card's balanced, although I think it is more fitting for entropy since it scrambles quanta similar to discord.
