I have found this deck archetype while looking for possible deck brews that can a base list for my future Standard deck brews. The deck is fully composed of Green creatures, with about a touch of Blue for a particular card tech: Arcane Flight. I do not really know the efficiency of this card, being only two copies in the deck. Maybe because it will let the biggest fatty get past through relevant blockers.

Anyhow, here below is the full decklist:

Maindeck
21 LANDS
4 Botanical Sanctum
10 Forest
2 Hashep Oasis
4 Hinterland Harbor
1 Island

The deck also caters the combo of Oviya Pashiri, Sage Lifecrafter with Mox Amber which will enhance the mana ramp speed of the deck. The deck finished Top 8 of a local tournament and you can find the rest of the decks here.
