Maybe you should just play it to understand, odd paladin or even shaman is way easier to play and progress with it, big priest is not about barnes turn 4, but whatever, does it matter to speak with you? Any arguments?
What is there to understand? A dog could play this deck the right way. You cheat your big minions out early thats the whole game plan. The only thing that can stop this deck is a bad draw or a aggro deck with a good draw.
The deck is by no means hard to play. Just overpowered and kinda rng sometimes.
And yes i played some games with this deck aswell.
