Alright, this is a build of Sac Land Tendrils, a notable budget Legacy deck. Now, despite what those words might imply, it's a very powerful deck, since it can just steamroll through hate and counterspells to pull out the win. I played the standard build for a while, and had a deal of success, however I wanted to know if it were possible to make the deck faster, even if at the expense of resilience. This was the result.
The key card is Lim-Dul's Vault which is basically Demonic Tutor here. After mostly-exhausting your hand, you can cast it to tutor for your wincon (Tendrils of Agony), or something else fun (Past in Flames, etc), and then cast one of your cantrips to put that card in your hand.
There are lots of lines of play, and a great deal of choices to make over the course of the game. I find it a lot of fun for those reasons, besides winning.
Owing to Lim-Dul's Vault, you're able to make a very toolbox or wishboard-like sideboard without sacrificing consistency in a major way. In fact, you could get away with running a lot more one-ofs than two-ofs if you wanted to diversify, but this is probably sufficient.
For more information on the archetype in general, I would recommend reading through the thread I linked above; it'll get you started a lot better than I can.
