somebody just found out the cards he agreed to trade are not of the quality or language specified in the trade. would i determine the fair trade? because of this, the value of his card dropped by three dollars. would i pick something that's worth three dollars out of his trades? he asked me to send first so i already did so. they guy is rude, and not good for my soul to talk to, so i want this situated as fast as possible. sorry for broken English, im not from the states.

I think you would totally be justified in asking for value to compensate for the condition. You agreed to a trade expecting around $X in value coming to you, so if that value goes down significantly due to condition your trade partner should fix it.
