If you get a Collective Company in your starting hand and enough mana to cast it, the game gets a lot easier.
If you DON'T start with CoCo in your hand, you still have quite a few options, you can start wailing on the opponent with efficient creatures (Knuckleblade and Mantis Rider are both quite scary). I've found that Reflector Mage isn't actually as strong as he seems due to the prevalence of ETB effects, but he's still very efficient creature removal (that is a creature himself). And of course Elvish Visionary is...Elvish Visionary.
Deathmist Raptor is the one card I'm not quite so sure about, I sort of want to replace him with something in my maybeboard.
The point of this deck is to hopefully play a Collective Company on turn 4, then start stabilizing your board. If you can manage to flip up Den Protector, even better. You can recycle Collective Company with that.
With the testing I've done, the only deck that gave me a REALLY hard time was Jeskai Black (though that particular deck, strangely, had no blue in it, making it a sort of mardu-lifelink-control. That version also had no Dromoka's Commands in it.)
The sideboard is for the following: Disdainful Strokes for countering eldrazi, Radiant Flames for wiping boards (usually atarka red), Suspension Field for removing big creatures, Dispel for control matchup, and Roast for that guy who always seems to draw all of his Thought-Knot Seers.
