I also use Claws of Valakut, they help boost my goblins just in case the game moves on past turn 5.

Have you thought about Summoning Trap or Lurking Predators as well? Lurking Predators works well in decks with Oracle of Mul Daya.

This is almost exactly my Goblin beatdown deck, except I have Wrap in Flames instead of Panic Attack, Bushwackers instead of Ragin Goblins, and Tuktuk :-)

Oracle of Mul Daya is a MUST card for any Omnath decks.

You're trying too hard to utilize the Ally multipliers, and you would be best reducing it down to about 6 different types of Allys, preferably in no more than 3 colors.
