So I have recently acquired a Crucible of Worlds Masterpiece. I got it back towards the beginning of Kaladesh when it was worth 80-90$ and it's recently gone up in value (sitting around 130$ currently). I wanted to know what your opinions are on its long term value? Will it go up long term being an eternal card with a limited print run at premium rarity, or should I sell it now while it's relatively hot? BTW it's going down about 1$ weekly pretty steadily.
