Merge Dragons Prism Flower method for getting new event dragons

Use this to get a faster dragon if you got 2 slow dragons for the event!

1) Buy a prism flower in the event shop for 10 gems (you only need 1)
2) Harvest the prism flower for orbs and dragon tree leaves
3) Merge dragon tree leaves until you have a vermilion dragon tree (preferably 2)
4) Harvest the vermillion dragon tree(s) for elderwood.
5) Merge elderwood to make tiny cabins for hedge gnomes
6) Merge bushes from the cabins until you have the bush wonder (preferably 2)
7) The bush wonder (The Ruins of the Sky Palace) will give you tanzanite mystery eggs, and maybe even a tanzanite mystery nest, which you can use to get more dragons.
