- Cards that can kill creatures with no regard to HP are frowned upon. The only card that does do this requires an existing status effect.

- Very few cards have power greater or equal to 9. This is essentially an insta-kill card as well WITH great attack power.

- It's a flying Owl's Eye, but Darkness. Unnecessary. Element shifts of existing cards is not a good idea.

- Not as bad. Makes Precognition obsolete though.

- A buffed version of Immortality creatures. Okay, I suppose.

- I really don't see the purpose of this. One rustler can use its ability multiple times per turn as is. Mass rustlers are redundant.

- Phrasing is awful. I think you mean that this ability deals damage equal to the cumulative total of the damage done by the target creature. This is overpowered, as just 2

for what is usually a lot of damage is out of proportion. Doubly so if it can be used multiple times. Triply so if it can be used multiple times on the same creature.

- Not bad, but growth creatures require an element other than the main card and then the benefit only applies to itself. This is essentially mini-blessing on a stick, and a mono card. +1/+1 would be more balanced.

- Thunder on a stick with great attack power. Probably not that overpowered given the high cost and high ability cost.

- A speedier version of infection, but with a high cost. Reasonable.

- Lightning on a stick. The ability to do 5 damage at will (2

is pretty cheep) is enough to one-shot most creatures. Two-shot most of the rest. The high cost isn't enough to offset the good HP and attack plus a powerful ability.

Other - Other elemented creatures are a bad idea, since one Nova gives 12 quanta, and Supernovas 24.
