This deck is kinda base on the concept of 5c humans.At first, I just want to build a deck that uses the same land and Aether Vial to cast zombies instead of humans, then I realize that we don't have enough cheap zombies, but only lots of 3drops: lords, Geralf's Messenger,Diregraf Colossus, Plague Belcher, I even thought about Anathemancer.Having too many 3 drops and lack of disrupt like Thalia means we can't just copy the concept of 5c humans.
Aether Vial did give you more creature per turn, but good Zombie like Cryptbreaker, Relentless Dead and Lotleth Troll are required mana to activate their powerful ability, zombies deck I used to build all face the same question, should I play more zombies or left the mana to those ability?But with Aether Vial, I can both activate abilities and play zombies. In this deck, the density of attack won't like 5c humans, but our zombies are much stronger than them.
Another big problem of zombie is there are too much 3 drops, much more than a normal aggro deck should play, so I think about Collected Company, coco allows us to summon 2 3drops as once, and instant also fits our strategy of leaving mana open.
So this is the raw idea of my 4c zombies. I don't know which 3drops is the best so I just want to test them all first.
I also want to try the synergy between Plague Belcher, Diregraf Captain, Wayward Servant, Geralf's Messenger, and Anathemancer. I think the etb deals damage effect maybe good enough to become the main strategy in a zombie deck.
