RG RAMP Hast Beatdown (Modern)

Not perfect, but the deck is working pretty well. Speed/Haste is the key to win.

You ramp with Elvish Mystic and/or Whisperer of the Wilds

Rhythm of the Wild make sure your creatures enter the battlefield and offer haste or +1/+1
Surrak, the Hunt Caller offer Haste and is a 5/4 hiter. No Trample, but he can become an issue fast.

IF Surrak and/or the Rythem of the Wild is on the Board, (this is the perfect scenario) you summon creatures and send them direct to your Opponent. In a perfect game, you start in t3 with sending surrak as first creature. And in T4 you send what the mana curve and hand allows to.

A Ghalta, Primal Hunger with haste is a problem for nearly every deck.

Soceries are to get blockers away or bring the damage directly in.

Heaven//Earth is against token and flyers, because the deck is not well prepared for flying creatures.
Colossal Majesty for Card Draw, will try Garruk's Uprising as replacement. Or one more Kiora, Behemoth Beckoner instead. We will see.

Maybe 2x Garruk's Harbringer for Carddraw and against black instead or Raging Kronch or Rubblebelt Rioters
Also Maybe 2x Shifting Ceratops instead of Arborback Stomper ( which is in the deck to restore Life, if ramp does not worked).
