>>21457533600 BST, 3-stager, and a type-based Immunity. All other requirements get #BTFO by something.
>type change on evolutionMetagross, Goodra, Hydreigon.
>Evolves at level 55, "high level", etc.Metang and Gabite evolve at 45. Sliggoo at 50.
>Appears at the end of the dexTechnically Beldum doesn't.
Hydreigon doesn't.
Kalos' dex is horribly disorganized, but even so Goodra and Garchomp are near the start of their dexes (counting Mountain Kalos independently)
>Immunity via typeGoodra has Sap Sipper which grants it an immunity. BUT, its not Fairy type for whatever reason (wouldve made a cool Poison/Fairy even with its current designs, with prevos being pure Poison.) and therefore discredits this rule. However, its literally the only exception.
>Flying>Dark>Steel>Flying>Ground>Dark (and was going to be Steel)Looking forward to gen 7 to break even more patterns.
Hell, Sliggoo even broke the 310->420->600 BST rule.
