Augments need some slight tweaking in the next errata, but not as much as some other cards.
1. MD Augment: I think her subtype should not be Magic Doll. It makes Doll rush too SP efficient and Command Dolls sacrifice abilities too efficient too. She should just be the Augments free revivor.
2. Overdose: Maybe make it so it can't target MD Augment or remove the +1 SP it refunds for being used on Augments.
3. Gaiasoul: Like Icy mentioned, maybe elaborate the condition as "If any sphere above 0, set one friendly unit HP = 0"
4. Augment Sorcerer: He is "Abyssal Forces" but shouldn't it be "Augment" according to name.
What do you think?
