It's okay, but there doesn't seem to be space to word the card well ("nearby enemy" doesn't make sense unless you read the notes) and "Widow Maker" is just a weird name for an ability. :p
Widow maker is actually a term for the very large pine cones, branches, etc. that drop from certain redwood trees, often from great heights. http://en.wikipedia.org/wiki/Widowmaker_(forestry)I can change the ability name to something else though... I thought it sounded kinda cool myself.
