Unbalanced cards

Hey guys, I was playing my inferno deck and kept losing some games. I think that all of the cards I lost to are pretty unfair since if I can't beat them then there must be a power imbalance. I just wanted to start some forum discussion so here are a few of the cards I think are way too powerful. For reference I was playing my Inferno deck. Since the best cards I opened are Inferno cards, if my Inferno deck can't win a game there must be some problem.

Adar-Malik
Griffin Battle Priest
Caller of the Void
Atropos
Wolf Justicar
Dhamiria
Ariana
Pao
Light of Tomorrow
Armageddon
Banshee
Bloodfrenzied Wyvern
Forbidden Flames
Ravager
Earth Quake
Strength of the Sea
Puppet Master
Gate to Nowhere
Kelthor
Dark Assassin
Abyssal Lord
Silent Death
Wolf Captain
Zardoc
Void Arbiter
Fireball
Eleonore
Ghost Dragon
Plague Spitter
Earth Shield
Yukiko
