Hey can i get any opinions on my magic deck?

Question

Main Deck

3 Manamorphose

3 Flame Javelin

3 Tarfire

4 Fire-Lit Thicket

10 Forest

9 Mountain

Sideboard

4 Gutteral Response

3 Vexing Shusher

the rest are blank and i could use suggestions to finish it

Answer 1

Add a howl of the night pack, a prismatic omen, a moss bridge troll and an over run and that should do it

Answer 2

Mainboard Shusher, its too good not too.

You dont seem to have trouble getting card draw, however mana excell is key in any green deck. Here are some of my opinions.

ADD:

+ 4 Lanowar Elves,

+1 Manamorphose

+ 2 loxidon warhammer

+  4 incinerate  

TAKE OUT:

tarfire

devoted druid

lashout

Unfortunatly this will leave you with 64 cards,  SIDEBOARD:

1) Firespout since second game you can find out if the opponent is relying on mass production creatures

2) Boggart just for lack of a better sideboard idea :P
