Unlikely Heroes

This deck is built around buffing creatures which grows on board by themselves (Bone Collector, Unlikely Hero, Seedling and Bloodfire Wisp). Haven't been able to get consistent results with this but the idea is kind of new and fun. It can beat yellow and red rush with decent draws but weak to removal and aoe in general.

Not sure about balance either, you can mix and match as you like. Seedling and Wisp are usually unplayable once you lose the board, Piper is to buff big creatures like Bone Collector or Wisp with low health after fighting.
