I got diamond now this deck really good

Bro i don’t know how to play this deck, i have to ask something to help me grew up and i think watch some gameplay is good to improve my skills or you never watch some proplayer play your deck? and i just ask him for some questions not all, you bruh.

Did you have a YouTube channel or something that i can watch and learn this deck?

Can this deck get me out from plat?
