I love on-curve-decks. The deck I had the most fun with so far (I’m playing Duelyst for over one year now and maining Magmar from the first day on) was post Shimzar and pre Bloodborn. It had no card draw and ended at 6 Mana. And it worked sooo good.
So I think I’ll try the first one first. 
Edit: Sister over Funsteel? I cut her nearly completely since the nerf.
