I have said this before but I will repeat it. We can tell you hundreds of good decks and we can tell you how to play them, but that won't have any effect when your playing ELO - experiance is what counts. Learn the concept of ELO, build your deck off this weeks ELO bans and play strategically.
Since you asked I'll share one of my favorite decks (it's a bit expensive)
Kerozinn Cr, Kusuri, Zhu Tang, Shifou, Z3r0 D34d, Bristone, Leviatonn (or use Klawz if Leviatonn is banned) and Methane
