reminds me of both Astral Communion and Nozdormu the Timeless, but on steroids. This don't discard your hand, and don't allow your opponent to go crazily insane first, and have 2 copies. Could fit in many decks, great counter to first few turns after played, especially with the nature of Druid, Draw and Ramp, with little card generation. Even have value against fast decks, if dropped early. I think this card will be nerfed soon. The only weakness this card has is after 3-4 turns, big decks can spam cards to overrun druid, whom's board clear is rather weak, But against value, or board clear heavy deck, it wouldn't be punished hard.
Special note to point out, playing this card will have your combo set up no matter what kind of combo you have. So if you can somehow ramp before 4 turns, they will most likely be death no matter what they play, great card in Wild, but doesn't fit Druid's theme this expansion.
