This is one of my favorite decks I've built and have been using for a long time, mostly in casual play.
This deck has stood against so many other deck builds, it's taken reanimator with ease stalling until an idenity crisis, or proteus staffing a blink moth into a duplicant, the mana ramp allows me to turn three wrath god or turn four akroma's vengence. It's a utility deck that survives. It's win condition is damage, and pulls a fireball incase your opponent builds a blockade to stop you. Solemn simulacru's can allow for a third turn extra mana, blocker, and draw power.
This deck is very persistent on not allowing your opponent to build a big enough creature or creature support base by always wiping the board and making sure your opponent is scared to drop creatures. If you need it profane command brings back a creature, or just adds to your utility.
This deck runs Proteus staff to ramp into solemns, bring out a baneslayer, or maybe duplicant. Often times I pull Akroma with the Proteus after the opponent has been hit with an Idenity Crisis allowing her smooth sailing into the victory. If she dies Profane Command her back.
Duplicant puts down a lot of big baddies simply by removing them, they proteus staffing them back into the deck so they may be used once more.
In all I've always had fun with deck, I've beaten Goblin decks with ease, Infect decks, mill decks, burn decks, though combo decks can be a huge problem.
During those times I find myself fighting combo decks, when I play a different form of this deck using Force of Will and Arcane Denial to keep better control early.
This sideboard runs some extra utility should you need it, like path to exiles which are a must, a third idenity crisis, and mortify.
If you find yourself fighting something faster, drop in 3 mortify and 4 Path to exile and take out 1 fireball, 4 akroma's vengeance, 1 supreme verdict.
Reanimator, I will drop in 2 cyclonic rift, and 4 path to exile in place of 2 supreme verdict,2 solemn s imulacrum, and 2 akroma's vengeance. The extra solemn is great to have but two is more than enough with baubles and you will likely put reanimator in the ground by stopping your opponents ability to sustain creatures.
In all this is my favorite deck to play, let me know if you guys think a few things need to be changed
