We already had quite enough 1-drops to make this work (at least a bit), so maybe…

[draft]Diregraf Ghoul
Grasping Scoundrel
Vicious Conquistador[/draft]

The problem is more with the 2-drops, but Guilds does give this deck some long game… and [card]Dead Weight[/card]. Granted, it’s no [card]Fatal Push[/card], but cheap removal is extremely important in a deck like this, especially since you have no usable discard.
