Any Hacked Pokemon, Hacked Events, Shiny Hacked events, Underleveled Pokemon, such as a Level 1 Gengar, even though Level 1 Haunter can be traded on GTS. Any Pokemon holding a Mega Stone cannot be traded/ Deposited on GTS, nor can any Pokemon with HM’s in your Party. True (Not Generated) Events cannot be traded on the GTS. Alternate formed Pokemon, such as a Mega Pokemon that is defauted in its Mega Form (You can do this through hacking) cannot be traded at all. Black/White Kyurems cannot be traded at all either.

I feel that I’m missing some Pokemon… Hacked Arceuses without Plate of Sprite type can be traded on GTS…

EDIT #1: Any Pokemon Holding MEga Stones, BW items, Not Gen 6 Poke Balls (Such as Holding a cherish ball) and Mega Stones introduced in ORAS (Such as galladite)
