What with Protean Hydra instead of Feral Hydra. Protean Hydra is can't be remove with damage with Forced Adaptation or Wolfir Silverheart. Then you also have Khalni Hydra and Primordial Hydra as cheap big creatures and too optimise your Overwhelming Stampede you can use borderland rager, sylvan rager, Greenweaver Druid or Farhaven Elf as mana ramp
