Need some advice

A description of what you want for the deck is great. Just saying help doesn't give us much to go on

I ain't an expert as I'm beginning in MTG, but you might want to add a play-set of "Temple Garden" to your lands. You only have 21 lands and you mana costs aren't in the lowest to say the least. (Even if you have those "Gatecreeper Vine" to help you.) You have a lot of big creatures or spells that cost 5+ mana. With such a low mana pool and no other ways to play those spells than paying their cost, they might be pretty hard to play effectively. So you might wanna think of a couple combos of cards that have a slightly smaller mana cost that you could put in play as early as possible to overcome your opponent and buy you some turns to gather some mana on the table.

"Thragtusk" is always a good card for a Selesnya deck. (Well, it's pretty good in most of green decks...) If you want a quick and cheap boost for your creatures, you should check for some "Rancor" or "Giant Growth". Cheap creatures are also pretty fun to play, like "Flinthoof Boar", "Young Wolf" or even "Wandering Wolf".

Remember, even if a card is good, it might not be good in your deck because it does fit or combo with your other cards. Always think about how you could combo a card to another. That's the most difficult and fun part of this game.

Hope it helped a bit because, as I said, I'm still a beginner.
Cheers !

PS : Being more precise in what kind of help you'd like would be good.

Thanks man

The biggest issue here is that you are probably gonna get mana screwed a lot. So many big creatures and you are playing with 21 land. That would work fine in most decks but in ur case I don't think it's enough. Get rid of the dryad militants and garuuk's packleaders, they aren't doing anything amazing for this deck and you could use the extra land. Also I could see mosswort bridge working in this deck.
