I am also concerned about this current draft.
12 gems on the spell, when you can choose the colour, is too many. You can target whatever looks highest on the board and be pretty sure of an extra turn. May not charge herself again, but with that link trait, can be sure to charge pretty much anything else.
Agree the trait is also a bit much, given that traits will always stack. I know the devs were looking into stopping traits stacking, but don't think that went anywhere.
I am also concerned about her being paired with Forest Guardian...
