Improve a Stompy deck

[rancor]

I have made an Stompy deck and I want to improve it. What I wanted is a very fast deck, enough fast to defeat zoo decks, low cost creatures and good ratio between skills, power and mana cost. This is my deck:

20 Forest
4 Strangleroot Geist
4 Llanowar Elves
4 Garruk's Companion
2 Scythe Tiger
2 Rogue Elephant
1 Drove of Elves
2 Dungrove Elder
2 Albino Troll
4 Pouncing Jaguar
4 Scute Mob
1 Khalni Hydra
2 Young Wolf
4 Rancor
1 Beastmaster Ascension
1 Call of Herd
2 Primal Bellow

I don´t want to perform a elves deck, I want a superfast deck. I will make a elves deck another time. Thank you very much.
