One of the better uncommon planeswalkers, 7 loyalty is huge and her ability only subtracts 1! Imagine playing this on turn 2 following a Llanowar elf, setting you up for playing a 5 drop on turn 3 and probably drawing a card. The single hybrid mana really makes her flexible, making her easily cast in any deck that can reliably produce single blue or green. All of this not even mentioning the possibilities with cards like Incubation Druid and Vannifar. Im in love
Cheap + mana ramping + card draw + high loyalty = recipe for success.
The synergy with Atraxa (who draws you a card off of this and restores a loyalty counter each turn) is especially notable...
