Mishra's Factory - 1996 Michael Loconto (4ED)

T: Add one colorless mana to your mana pool. 1: Mishra's Factory becomes an Assembly Worker, a 2/2 artifact creature, until end of turn. Assembly Worker still counts as a land but cannot be tapped for mana the turn it comes into play. T: Target Assembly Worker gets +1/+1 until end of turn. Not a Tournament Legal card.
