Covenant Stone (i got the idea from a pokemon hack called Storm Silver), which if all requirements are met, you use it on that pokemon and it evolves. It can be toggled on/off in server config, to make it regular trade evolutions.
Next, would be a CRAFTABLE porygon!
Recipe:
1 AI (crafted with 4 Nether Quartz, 1 Diamond, and 4 Lapis)
1 PC
1 Thunderstone
1 Fire Stone
1 Water Stone
It gives you a Virtual Egg, (a red/blue Dragon Egg reskin) that in about 2 minecraft days Hatches into a Wild Porygon.
Much Love, and thanks for checking this out, Mr M. / SPG/ Anyone who likes pixelmon!
