Inexorable Tide, Joiner Adept, and the Vivid lands e.g. Vivid Grove are all really good additions, and not all that expensive either. Aside from being three colors, for Ramos, may I ask why Derevi, Empyrial Tactician is in your list?

Hi cgannon, this is the deck i've tested so far. A combination of the cards that i already have and some cheap ones i've bought for testing. It was surprisingly strong already, so i am determined to make it better.

I am currently adding Animar, Soul of Elements, Winding Constrictor and Marath, Will of the Wild.
Derevi, Empyrial Tactician will probably leave the deck, but i need to cut a lot more cards.

Thank you for your suggestion. I think i will add them all, but i have to look which card will leave the deck.
