MTG Salvation

Hello Magic lovers. This week I negotiated with a seller who was looking for $ 2,200 for a sealed box of Tempest. I spent 3 days analyzing the Tempest market, but it is so confusing that even I don't understand. I gave him an offer of $ 1,950 since it was really risky, as I don't know if Tempest can grow or stagnate at the same price. Yesterday he said he would close the deal with just $ 2,050. I was so indecisive that I came here to clear my doubts. So, is $ 2,050 worth a lot for this sealed box? Or at this price can I buy something that will really make a profit for me in the future?
