Elf Eldrazi

this deck got to 37 - 6 in mws. i know that many players there arnt really good but i did face a lot of popular decks : jund , vampires , rock ,anything with baneslayer ( lol) and in many cases i won. the only weakpoint about this deck would be mass removal and baneslayer abysse dude. that is why slingbow trap is in the sideboard( i know the card itself is horrible but unless i splash a color its the best removal for bane , avyssal , vamplord that i can get) and i think its better then windstorm because i can kill a bane with 4 mana and play the eldrazi monument faster at which point a bane wont make a big diffrence. sideboard: acidic slime is a great card and ic an easily play it on turn 3 destroying a land or an echantment. great stable stag is there for vampires and any blue deck with shroud. relic of progenitus is there for the swamp combo deck and for knight of the reliquary. naturalize agaisnt artifact decks and the spreading seas enchantment. mold shambler is there for planewalkers. p.s yes this deck has in off lands. maybe i should even take off some. thanks in advance for any sugestions. and a question should i splash a color for some removal? green white or black green
