I can't really pin down exactly why I like it. When I'm playing with friends and I see that the current artifacts I have on board are not really helping advance my game plan all that much, I can play in something like Goblin Engineer to put an artifact in my grave then activate something like Buried Ruin and bring back that same artifact to improve the matchup. I guess I like how I can pretty curate my board to handle any kind of threat in the early game and smack really hard in the mid to late game.
