What really sets him apart from other Dimir commanders for me is the sacrifice ability
So if all you were doing with Ivy was copying Cerulean Wisps to draw two cards, this list wouldnt make my list at all
Jace sets you up well while getting you value, he bounces their things and restores your tempo and he locks people out of the game by denying them relevant draws
Other interesting Magic actions rooted in these early Alpha, Beta, and Unlimited sets include looking at your opponents hand (Glasses of Urza), having an infinite hand size (Library of Leng), and casting modal spells (Healing Salve)
However, in more powerful pods, that kind of thing is happening all the time, and being able to both create treasures and draw cards with this enchantment is going to feel great
