I am willing to trade good cards for bulk on my trade list but you have to add value.  I will not trade a Force of will for 95 one dollar cards on my trade list.  Having said that i will not bulk trade for dual lands.  I will however trade duals for power if  offered.  Please dont ask for a trade where i am giving you $70 card and you are giving me $65 in rares.  I will cancel this trade without looking at it.
