[Meta thread] Iron's PokeRole Adventure: The Skull Ruins

[Iron]

Noticed the Surprise of them getting Super Luck at Full Happiness, and it reminds me of the Dragonair Yang with his Double Ability and Metagross with access to his regular Ability upon Mega Evolution. Did you get inspiration from those ideas, or did you have that planned before I came up with my own. Just curious, mate!

I don't know what those things are. 
Usually what happens is I think of a story-based trait first (the statue thing came from the 90's Gargoyles cartoon + the Pokedex entry + underground cavern imagery). Then I sometimes think of a mechanical way I could express that.
