I honestly don’t know if you can win tavern brawl week 13 with a basic deck. Not having access to the Deathrattle minions from Curse of Naxxramas is a huge disadvantage. You’ll quickly find yourself getting run over by Warlock and Hunter. I did get a win with this deck, but my EU account is fairly sparse in terms of cards. Loot Hoarder is great for card advantage, and Piloted Shredder is a monster in this Brawl. Polymorph is needed for cards like Sludge Belcher that would be extremely difficult to deal with without it. Flamestrike will hopefully help get you back in the game, but if the board is filled with Deathrattle minions it might be too late.
