I'm going to assume that this is a first or second draft of this deck, as it is extremely lacking in focus. Try to
shrink it down to focus on one thing, with a second as back up. To assist with this, I'd advise looking up a Standard format legal G/R Dragons deck, and then replacing some of those cards with Modern cards.
If I was to run a Modern legal G/R Dragons deck right now, It'd look like this.

forestThis deck basically took what I liked best about my G/R Dragons standard deck, went a little lighter on recursion and value, and got more aggressive. As before, your deck is all over the place with both Atarkas, various enchantments, creatures which get bigger if you have more lands, random mana ramp etc. Try to focus your efforts on a singular area for your deck.
