White Black life drain Competition (Standard)

So the new set of Shadows over Indistrad comes out and is a real show shocker with lore and some pretty good cards to last. Werewolves are hot off the block with a powerful aggro play style. Also, zombies and vampires are back on the rise, but I think eldritch moon will have the other half of the combos. So I bought a fat pack and opened up some cards and decided to make a deck that was interesting to play while taking advantage of some mechanics introduced. This deck is made to be passive aggro, conflicting natures but playing with your opponent like how white black should be played. The low mana cost of the deck is to keep things on the board to challenge your opponent, while also being able to quickly combo off for insane damage. As you take a look at the deck you can probably see that most of the action happens at the beginning of the upkeep. Zulaport cutthroat is chosen over kalistrate healer because zulaport isn't just damage it's also insurance to make opponents not want to kill your creatures. I suggest playing it passive and saving mana for quick responses. Also another thing to consider is that if you don't have the mana, then discard it! Defiant blood lord makes the deck insane at changing the playing field and will probably end the game for you, but if the mana isn't there he's just taking up space. Also don't be afraid to cut lose ends if it doesn't work then play to what does. Also tip if the opponents is playing creatures or instants when you activate creeping dread discard those cards, but I don't sugest having more than one on the field. Final tip at the beginning of the upkeep[blank] cards can be activated in any order you wish Example: 1st asylum visitor one, 2nd creeping dread, 3rd asylum visitor two.
