Crystalbound Immortal - Crystal Chacu

Emerald Tortoise allows Chacu Challhua to attack directly, then switch to defence position to deny the opponent their battle phase.
Summoning it out via Crystal Promise and Carbuncle getting 2 bodies on board quickly and easily to Tribute.
All whilst making use of Ancient City being indestructible, making up for the Earthbound Immortals weaknesses. 

Still working on card numbers, might make a few changes. Would love to trim the deck to a neat 40, and include a 2nd Revival, but will have to test things. Also sideboard is incomplete currently, need more time with the deck so I can decide what needs sideboarding to help with it's weaknesses.
