Ive now been in more than a few games where the best thing you can do to move a game along is to make a clone of an opposing Orcish Bowmasters, just to take it off the battlefield
Not only are you immune to their mana denial, you have a mana denial plan of your own that the opponent must respect
so many times, Go for the Throat or Doom Blades restrictions feel terrible, and Parting Thoughts doesnt have that problem
The drawback of also providing an opponent with three cards will feel pretty terrible if your game is down to two players, but the rest of the time, youll often be in a position where those cards could be granted for favors (Dont attack me for the next two turns!) or in order to help another weaker player take down the table threat
For example, the siege subtype lets you basically assign it to an opponent to protect, then everyone else can attack it and it transforms into the backside when it's defeated
Im not entirely sure what sort of mono-black artifact deck Im going to build around Trazyn, but Im probably starting with Commanders Sphere, Gilded Lotus, Mirage Mirror, and Lithoform Engine
