This is Jace's Angels, a control deck with Tamiyo, Jace and Entreat as it's win conditions.
As always, please feel free to leave commets, criticism or suggestions! I'll try to consider or possibly respond with my reasoning to all.
Mainboard:
Creatures
NONE! That's right, this runs ZERO creature cards. Control at it's core!
Sorceries
Supreme Verdict - An uncounterable board wipe. This will keep the board clear and let you swing in with your Azorius Keyrunes after if you so choose.
Terminus - There is nothing bad about clearing the board in a way that doesn't play into Blood Artist's hands. This is a great way to prevent returning zombies and avoid indestructible effects such as Rootborn Defenses.
Entreat the Angels - One of your win conditions. Big, beefy 4/4 angels are hard enough to deal with, let alone about 4-5 of them off of a miracle, or still a solid 2-3 off of a hard cast mid-late game.
Instants
Think Twice - You won't see many blue decks not running some of these. Awesome cantrip for mana you may have saved for Syncopates or other counters.
Azorius Charm - This thing does it all. Timewalk, draw or lifelink for your angels in a pinch!
Essence Scatter - Most decks in the current meta are aggro-based, so having an essence scatter is a strong singleton or even two-of in a lot of control decks currently.
Sphinx's Revelation - Blue Sun Zenith without the shuffle that gives life. Two-of is just right for this card.
Enchantments
Detention Sphere - This is what happens when you let Oblivion Ring smoke crack.
Oblivion Ring - But we need a few sober ones in here.
Artifacts
Azorius Keyrune - These things remind me of batman. Mana-fixer by day, 2-2 removal resistant flyer by night! Seriously, they fix mana, provide a creature on command, and are competitively costed.
Trading Post - This thing is AMAZING with control. Pay a mana and life for a blocker, or pitch cards you don't need to get your life up if you've been taking a beating! You can even sac a goat to get keyrunes back.
Elixir of Immortality - I've actually LOST on occasion to decking out! Usually this happens in a mirror match. A one-of of this will help me reset my deck and keep pushing for a win! Will also help with some life in a pinch.
Planeswalkers
Tamiyo, the Moon Sage - She has been a staple in blue for a while now, and with Return to Ravnica, that's no exception. Her ultimate wins games and her presence instills fear.
Jace, Architect of Thought - To be honest, I'm considering running four of these guys. I can't think of anything bad to say. Mini fact or fiction? SURE. Bribery on the opponent and yourself? SURE. Stall against weenies? SURE.
Land
Yes, I'm touching upon land for a moment. The biggest question I'm going to likely get asked is: "RedSeries, WHAI FOR Azorius Guildgates?"
Easy, mana fixing (drop this turn one) and a card that I don't feel remotely bad about pitching to Trading Post.
Sideboard
Geist of Saint Traft - This thing win games. Lots of games. Great in a mirror match.
Nevermore - Want your opponent to not cast their best spell for a while? Here's how!
Witchbane Orb
- Every now and again you get an oddball curse deck. This helps against any burn that might pop up and stops Blood Artist in it's tracks.
Negate - Mirror matches suck.
Dissipate - Zombies suck more.
Grafdigger's Cage - Really. They suck a lot more.
Knight of Glory
- No really, I hate zombies.
