I would make these cards myself, but I don't have enough free time to start designing art and all other stuff, so maybe someone with more time can steal and do this.
Jack-of-all-trades | SpecialistType: Creature
Cost: 4
| 5
Stats: 2/3 | 3/4
On every turn Jack-of-all-trades gains one passive and one active skill with random cost (between 1-3 quantum) and loses all previous skills. (for example: When played it gains venom and 3
burrow, next turn it has airbourne and 2
ablaze and so on..)
Specialist (upgraded version) works the same way with the additional skill:
pay 3
to stop changing skills (so you could stay at skill that you like/need).
Landslide | Rolling stonesType: Sorcery
Cost: 7
| 9
Landslide turns all pillars/towers (including opponents) to 2/2 creatures until the beginning of your next turn(they still generate quantum).
Rolling stones turns all pillars/towers to 2/2 creatures permanently. Color of creatures is same as quantum they generate.

On every successful attack rogue steals one card from your opponents hand into your hand.
