This is my take on a Junk Midrange deck, which utilizes tokens swarming the field and getting bigger with Voice of Resurgence, Brimaz, King of Oreskos, Elspeth, Sun's Champion, and Archangel of Thune.
Sylvan Caryatid - This card is the best mana ramp in the game. Any color can be a big help in a 3 color deck.
Voice of Resurgence - This card is great. It can become a huge threat from the very beginning. The rest of the tokens in the deck can help this card become even better when you combine the different tokens with the ability of Archangel of Thune.
Courser of Kruphix - This card is an amazing card that helps you filter through your deck faster, offers lifegain and it works amazingly with underworld connections.
Brimaz, King of Oreskos - This card helps with swarming the field very quickly and he is a very strong 3 drop. This coupled with his tokens and Archangel of Thune's ability can get really out of hand.
Archangel of Thune - A big boss of the deck, this card makes everything get very out of hand. This makes everything bigger and bigger and it makes your life total go higher and higher.
Blood Baron of Vizkopa - This card is immune to most forms of removal and can be a huge pain to a lot of players in current metagame.
Obzedat, Ghost Council - Another powerful monster and a good source of lifegain. It also puts the opponent on a 10 turn countdown.
Thoughtseize - this card lets you take a nonland permanent out of your opponents hand, and see their whole hand. 'Nuff said.
Devour Flesh - This card is early removal that puts your opponent in a sticky situation. It can also get rid of things with hexproof.
Abrupt Decay - This card is my favorite removal spell. There are a lot of 3 cost cards being used in current metagame and it can put an end to them quickly and it cannot be countered.
Banishing Light - This is more removal, but it can also effect gods, artifacts, or enchantments.
Underworld Connections - This card is a hero of the deck. It may cost a life to draw a card but with all the lifegain in this deck, that means nothing.
Hero's Downfall - This card is the strongest fork of removal that can get rid of all creatures or planeswalkers. It's an all around great card.
Elspeth, Sun's Champion - The biggest "out" in the deck. It can end the game very quickly with it's tokens and that couples with [Archangel of Thune]], things can get even worse.
Sideboard
Ajani, Mentor of Heroes - This card has moments where it can do very well, such as against the control matchups.
Bile Blight - This card is good for token decks, or decks with a lot of copies of the same card, such as Elvish Mystic.
Deicide - This card basically shuts down mono blue decks.
Erebos, God of the Dead - Does great against decks that rely on lifegain abilities.
Lifebane Zombie - This card is a hand removal card that let's you look at the opponents hand. Couldn't be better for control matchup's and even red/green monsters.
Mistcutter Hydra - This card can change a mono blue matchup and make it almost impossible for them to win the the right situation.
Nyx-Fleece Ram - This card is a hero against burn deck's.
Thoughtseize - An extra one if it is ever needed.
Whip of Erebos - This card helps in games that involve milling and even in games that last a long time.
