Is my G/B elves deck good enough for FNM?

Returning player after long absence, i'm really bored of my red aggro deck so I thought I would give this a try. Only one Nissa because I only have one.

Any feedback? Don't want to buy chord of calling as it wont be standard long. Thanks.

EDIT: Forgot bellower can't fetch Nissa
