Knife Artist is basically saying "You can either do one of four things: 1) swing with Kunai and pass, swing with Kunai, 2) equip another one of your stored-up Kunais and swing again, 3) swing with Kunai and equip another weapon from hand and swing, 4) immediately equip another weapon and swing twice. So it is more than possible to use her with other weapons.
Rising Dragon Fist, I have less spell-copying than minion-copying, generally speaking. I'll keep an eye out for other feedback but from what others are saying, so far, maybe 3 mana... but then it's rather weak at first.
Gift of the Lotus is good (as is all the other suggestions from others).
On to your cards:
So, Darkflame Tome, how easy is it to abuse with Malygos, do you think? Two of these with Maly is 28.
Heroic Sidequick > Sidekick. Also suggesting a 2/2 body.
I think Climax is generally fine. It's not good against tall boards, and against aggro, you likely will not make it to turn 9.
At this point, I must ask. Where are you getting your card art? It seems to be from another game, from what I can tell.
Power level between Living Rose and
Awoken's Rail Spike Jadebark Staff seems to be pretty drastic. Maybe make Living Rose easier to do?
You can stand to give Prima more stats since her card text is technically a negative.
Foretelling, I reckon draw 3, draw 2 more, or 2 and 3.
Raven's Eye, pretty weak.
Primordial Wind, do you have Spell Damage support? If not, can go to 6 mana.
Twisted Bargain... hm. Honestly pretty hard to balance. I suppose it's ok...? Maybe wait for more feedback.
