White Kill deack help.

[oliver78789]

I was recently inspired to make a white kill deck from my teacher, hehe. Well this is what i have so far, any comments or advice would be greatly appreciated. ( Basic strategy of the deck is to just annoy my opponent by killing stuff, the shadow creatures are for some dmg inorder to kill them. )
