Trying to jam 4 colors in SoI Standard seems absurd, considering we don't even know the rare land cycle. Drana, while great, requires you to draw one of your six black sources, her, for her to survive on the board for a turn, and then to deal Combat damage to a player to get value. Innistrad has all the spirits that are going to make Drana be less effective IMO.
Collected Company doesn't work with 19 Creatures or Equipment in general, like at all. I run CoCo Hatebears in Modern with 30 Creatures and I still whiff about once every 4-5 Games, and you're running 2/3rd of what I do. Collected Company wants Dudes, and it's honestly not that great in this deck with the equipment/Non creature spells.
On top of that, CoCo is only good when you can get the full value out of it. If you get two one drops for 4 Mana, you feel like you wasted a card. If you get two 2 Drops, you've achieved Mana Parity. If you get 2 3Drops, you've gotten full on value. You should be aiming for that 2/3 Drop spot in building a deck with CoCo.
If you want to go CoCo Allies, You'd be better off skipping the Black, going Naya, focusing as much as you can on Rally/Cohort Value. Going to Combat, you CoCo during declare Attackers, ripping off a Firemantle Mage and a Lantern Scout getting all that value.
