Hi,
I also like the g splash but adding Tarmogoyf and cutting things like TS, SP is way to weak against decks like Miracles, Elves, S&T, ANT, Burn etc.
With this configuration your fair decks MU like UR Delver, UWR, TA, DnT etc gets better because of your high creature count and bigger removal package but it`s to linear for my taste.
Having completley no acces to Wasteland is also a point which I dont like because even if more people play with basics, Wasteland will never be a dead card because you can respond to PoP with it for example or can shut off things like Port, Caven, Cradle or Sol lands...If you want to up your pressure I think Delver or Clique would be a bit better for this deck even if they`re not bolt proof.
But well if it works out for you (maybe in a fair heacy meta), then go for it...
Greetings
