Answer 1

need to focus more on the zombies, more card of safe return. zombies are the best swarmer ive seen and a lot of its based out of the graveyard, so 3 card of safe return works well.

alot of unnecessary cards in here. especially the magic and traps

Answer 2

Take out Exiled Force and add more Cards of Safe Return.
