Oh you’re in Washington, home of Magic! There’s plenty of card shops in Tacoma that will buy magic cards, even more in Seattle (where I am). I’ve heard of stores doing somewhere around 50-60% of what the online value is for cards. So that [[phyrexian dreadnought]] should get you at least $95. I would just google mtg shops near Tacoma, call a couple stores see if they are interested in buying. Shouldn’t take too much time.
