Esper Teachings(Mystical Teachings deck) control deck. I love control, I love Esper, and I love toolkit decks, so here you go.
I also created the Esper Gifts deck http://tappedout.net/mtg-decks/sorry-i-only-found-2-cards/ for fun, and it worked out fairly well. I'm going to a local modern event, however, and I wanted to build something more serious and consistent. Hence, Teachings. Mystical Teachings is an instant speed tutor card. He'll get your win condition, he gets you board wipe (Consume the Meek), he gets spot removal(Path to Exile, Go for the Throat, Dismember) and counterspells for the combo matchup or to stop important plays(Cryptic Command, Rune Snag, Mana Leak). It gets what it wants, when it wants, and without giving your opponent a choice. Teachings also has a flashback cost, so it's a consistent tutor even in the later turns, akin to a deck-wide Think Twice substitute for a mana sink.
Your win conditions is Teferi, Mage of Zhalfir and, more often than not, in conjuction with Creeping Tar Pit. He limits the speed of their removal, which makes combat phase much safer. He stops combo decks, and makes your counterspells the final say in any war. At 3/4, he can lay on a little damage turn by turn, and have enough toughness to chump block key cards. He also gives Wurmcoil Engine flash(in your library), and allows Wurmy to be tutored up and flashed in EOT. Being that Mystical Teachings can fetch any instant speed card anytime, your sideboard is opened to a lot more 1-ofs. Tar Pit also wrecks planeswalkers that choose to show their ugly faces. No blocks, buddy. The only Planeswalker walking away from this guy is Karn Liberated, and you should have picked him off with Mana Leak, Rune Snag, or Thoughtseize.
This deck doesn't like Emrakul, the Aeons Torn. I don't think any deck does. So I run a singleton Mindbreak Trap in the sideboard. Teachings for Mindbreak, wait until they do his hardcast shenanigans in Tron, and say no by exiling him on the stack. Mindbreak Trap also stops U/R storm.
Stony Silence gives eggs an anal.
Timely Reinforcements makes RDW and Zoo cry. A lot.
Vendilion Clique makes combo cry. Harder.
Then there's just the standard extra sweeper, alternate win-con, and defense against affinity.
