G/r ramp

[poppa_f]

I'm considering playing G/r ramp/devotion post rotation. Strategy basically to ramp in to big threats, ideally some permutation of Xenagos +1, Nykthos/Voyaging Satyr, Nissa +1 to make a huge mana pool, then power out a big Genesis hydra / Polukranos / Hornet Queen / Crater's Claws.

Provisional deck list:
[deck=G/r ramp]
Creatures:23
4 Elvish Mystic
4 Genesis Hydra
4 Voyaging Satyr
4 Courser of Kruphix
1 Nylea, God of the Hunt
4 Polukranos, World Eater
2 Hornet Queen

Spells:13
4 Crater's Claws
1 Setessan Tactics
4 Xenagos, the Reveler
4 Nissa, Worldwaker

Lands:24
10 Forest
2 Mountain
4 Nykthos, Shrine to Nyx
4 Temple of Abandon
4 Wooded Foothills

Sideboard:15
2 Setessan Tactics
1 Bow of Nylea
3 Hornet Nest
3 Reclamation Sage
1 Roar of Challenge
3 Nylea's Disciple
1 Burn Away
1 Garruk, Apex Predator[/deck]


I'm a bit worried it will be too inconsistent though, especially
against hand disruption (can see games where you just get dorks / flood out), so I'm also considering an alternate build that has more red, no Nykthos, less dorks, but hopefully is more consistent:

[deck=G/r ramp 2]Creatures:24
4 Elvish Mystic
2 Genesis Hydra
4 Sylvan Caryatid
4 Courser of Kruphix
4 Goblin Rabblemaster
2 Polukranos, World Eater
4 Stormbreath Dragon

Spells:12
2 Crater's Claws
2 Lightning Strike
2 Chandra, Pyromaster
2 Xenagos, the Reveler
2 Nissa, Worldwaker
2 Sarkhan, the Dragonspeaker

Lands:24
9 Forest
7 Mountain
4 Temple of Abandon
4 Wooded Foothills

Sideboard:15
2 Scouring Sands
1 Barrage of Boulders
4 Hornet Nest
3 Reclamation Sage
1 Roar of Challenge
2 Arbor Colossus
2 Sarkhan, the Dragonspeaker[/deck]

Not sure if it's worth running Rabblemaster, alternatives could be Ashcloud Phoenix, Fanatic of Xenagos or Heir of the Wilds maybe?

Which deck do you guys think looks strongest?
