This may soud crazy but here's an idea: Splash white with Temple Garden (still a forest) for Karametra, God of Harvests . It'll help you're land rampin' fo sho! You could also perhaps add just a few Sunpetal Grove for more mana fix potentially.

THX for the idea! I have already considered splashing in a second color, but actually there is enough ramping atm in think While this is a Combo deck, it still needs a beatdown plan without golems Are there any essential creatures I'm missing? I won't play Goyf due to it's price, but what do you think about 1 vor 2 Scavenging Ooze ?

Try running 2x Beast Within for the last slots in yer SB. It's pretty versatile and could even help keep you on the beatdown plan like if someone tries to kill one of yer guys you can beast it and get yerself a 3/3.
