At the onset of Modern, there was a Temur tempo deck featuring Delver of Secrets, Tarmogoyf, and Huntmaster of the Fells. That style of deck was since invalidated, in large part due to the format becoming so fast that it wasn't really possible to play a Spell Snare, Cryptic Command deck. However, the format is shifting away from things like Infect and Affinity and towards decks like Tron and Primeval Titan variants. That means that there might be an opportunity for a Temur midrange deck to come back to the forefront:

Huntmaster of the Fells has gotten much more powerful in this deck with the addition of Opt to the format. That makes it much easier for you to control when Huntmaster flips, which makes the card much easier to leverage in grindy midrange matchups.

Engineered Explosives gives you even more game against decks that are trying to stay low-to-the-ground, like Affinity and Bogles, while Blood Moon is a haymaker against a lot of the unfair, big mana decks. Add in the suite of Mana Leaks, Spell Snares, and Cryptic Commands, and you've got a lot of cards that can steal games against almost any deck in the format.

All in all, this is a very flexible shell that you can tweak to fit your local metagame. If you're looking for a deck featuring Snapcaster Mage, Tarmogoyf, and Lightning Bolt, this deck is a great place to start.
