While X sadly cannot be 0 here, the or less clause is a nice inclusion allowing Thieving Skydiver to be kicked for 1 and still steal powerful, zero-mana artifacts such as Stonecoil Serpent, Hangarback Walker, and Mox Amber
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
Only two normal cards remain valued above $10: Everybody Lives
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
So if all you were doing with Ivy was copying Cerulean Wisps to draw two cards, this list wouldnt make my list at all
Unlike Cryptolith Rite however, this new Creature Enchantment comes with some staying power
