I'm fair when trading my Arceus. I trade them for a rare or holo usually, since that's how rare they really are. I don't rip people off. Sometimes I even give myself the disadvantage because I like helping people out, I know people need their cards and how hard it can be to get them. One time I just gave a guy a Bebe's Searchfor free because he didn't have anything of the same worth that I wanted and I have a million Bebe's. At an Arceus prerelease once this guy (a master, oddly enough) wanted my metal energy. He had few cards, and I told him the only things I'd be interested in were his Dusknoir DP and Staraptor FB Lv.X. He offered to trade one (or maybe it was even both) for the metal energy, but I said no, your cards are worth way too much for a metal energy. So I just gave it to him for free, due to its little worth and again my abundant stock. Okay, sometimes I'll kinda make an unfair deal, but that junior said they didn't need or want their Uxie or Rare Candy even after I told them its worth and use. I still gave them 2 holos and a Heat Rotom for the Uxie and some kind of rare and holo energy for the Rare Candy. The point is I don't like ripping people off, for I've been a victim on the other side of the trade (jerk traded me 2 Pachirisu GE for a Delcatty PL, a Blastoise PL AND my only Claydol at a Platinum PR), and I just feel better being nice to people.
