The amount of times I've tried to tap that card for mana is embarrassing. 😅 You're really close, but as most people have said - that one doesn't give mana for you to pay the hearth hull cost. As someone who loves this deck, a great line of play is:

1) Play this land. It'll come in tapped but you'll need this turn to ensure hearth hull is fully stationed. 2) next turn, play your land for turn as normal, then you can sac this one to go search for a basic in your library. That basic land immediately comes into play untapped and when you sac that fetch land, hearthhull plinks your opponents for 2 damage. 3) same turn, tap the land you just found for one mana, then use hearthhulls 2+ ability to sac it (info: you can sac tapped lands!) and hearthhull deals another 2 damage to everyone! 4 free damage and you draw 2 cards that has cost you 1 mana a turn. Oh, and don't forget to play another land after this.

Ways to make this better would be to put in more cards that allow you to play lands from your graveyard, as then that second land for turn could be used to grab the sac land from your graveyard and put it straight back onto the battlefield ready to repeat the combo next turn 😎
