Deck is based on Primalcrux, Spitting Image and Parallel Lives.

I would like this deck to work efficiently and quick, it needs some adjustments for that to work I think.
Advice is very welcome :)

- With Sakura-Tribe Elder and Harrow I hope to have 6-7 mana in turn 4.
Sakura gives me a body that will lend green mana to Primalcrux and makes my Khalni Hydra cheaper, it's also a nice target for a Rite of Replication. I choose Harrow above Skyshroud Claim because i can use it to search for the islands. Land that i sacrifice for harrow is retrievable with Life from the Loam.
- Seek the Horizon gives me three landcards in my hand. I like this for Spitting Image.
- Oracle of Mul Daya more land! I just wonder if this card is really helpful...?
- Eternal Witness brings back my cards that I tossed with Harrow, Spitting Image and dredgen of Life from the Loam. She also gives 2 green mana to my crux and can retrieve creatures in a pinch.
- Giant Adephage, Spitting Image, Rite of Replication make the heavy tokens and Parallel Lives dubbles them.

I splash with 2 islands and 1 Flooded Grove  (I only need 2 blue mana for Rite of Replication). I wonder if this is enough?
I'm also looking to see if I should put in more special land like Rogue's Passage, Simic Growth Chamber, Ghost Quarter, etc.

I'm also wondering if some cards from my sideboard should be put into the main board and if the numbers of all the cards are right this way.

Any form of advice would be very much appreciated! :)
