So looking at some quick and dirty math, if you have ~40 enchantments in your deck you'll have about a 98% chance of getting 1+ off her first ability, 85% for 2+, 59% for 3+, then 28% for 4+, and under 10% for 5+
Definitely seems good, especially if you can blink her. The tap ability is cute with how she's basically the only one who can wander Duskmourn without issues, and it can definitely cheat some rooms open, but it seems a lot more niche.
