On all the cards, you are lacking the casting cost and the ability costs. But let's review.
- As material creatures are much more common than immaterial, I don't see how this would benefit me. It would only work against a mono-aether deck, and that kind of card belonging to aether does not make any sense. In most cases, this will remove immortality from a handful of creatures, but make many MORE immaterial. Rework this.
- An average of 12 attack per turn should carry at least a 12 quanta cost. Even so, 24 damage out of the gate is excessive. How would this stack with Adrenaline? Tone it down some.
- We have the Aether Nymph for this already. Rework this.
- to the...? What? I'm assuming the opponent, but would that be worth the 10 HP cost? I'd rather keep the 8 attack creature than sacrifice it. It'd be a finisher at best. However, a few of these together could 1-shot a player. 3 of these could deal 84 damage in two turns. Rework this.
- No insta-kill cards without regards to HP or abnormal status. EVER. But this on a 15/10 creature?! Are you nuts? A creature with those stats and no ability would be 18 quanta at least. WITH the ability it would be an "I WIN" card. No, just no. Rework this.
- You spelled Chaos wrong, as previously mentioned. But this would be too unpredictable to use. Pandemonium and Chaos Seed would be better than this. Fine tune this.
- So it's the Infection ability with 1 damage up front? A bit boring... Rework this
- I kinda like this one, but the ability needs rephrasing to be more professional and concise. Fine tune this.
- Kinda weak ability. 10 HP isn't going anywhere any time soon. This is more likely to be mutated, frozen, or rewound than firebolted or the like. Rework this.
- No insta-kill cards without regards to HP or abnormal status. Holy Light does something similar, but it's a spell. This is an "I WIN" card against any
deck. Rework this.
- So it's a weaker freeze. Okay I guess...
- Does an average of 13 damage? Make the cost really high. But even so, 18 damage in one turn is pushing it. Make the ability cost high too.
