u/E-Lazy

Hello everyone - I started playing mtg and my friends recommended me pauper - I have been to several tournaments already (I do not know where elese to play other than local Hareruya store) - I have been loosing since to the same mono red deck with artifact lands. Is everyone playing the same deck? Are there any ways to practice other than this local club? Don't get me wrong - I expect to lose games now, but I am kinda tired seing the same deck 3 weeks in a row (all different players)
