Get more mana ramp and take out the random cards in here such as protean hydra. If your interested in having some non eldrazi big creatures avenger of zendikar works well with khalni garden. Also take out Ulamaogs crusher (not a very good card) and hedron matrix. If your going for summoning trap take out the eldrazi conscription. Get another oracle and some more archdruids/priest of titanias another treespeaker and possibly arbor elf for more 1 drops.
