Who Should Ash's Sixth Kalos Region Pokemon be

After looking at the reports of upcoming Pokemon episodes that are yet to be dubbed in english reveal Ash's 5th Kalos region Pokemon to be a Goomy

The most unexpected yet disappointing Pokemon for Ash to catch in Kalos but instead of complaining over it, we better get intouch with the Japanese company incharge of producing these episodes fast and convince them on who we want Ash's 5th/6th Kalos Pokemon to be and we want his 6th pokemon to be one that mega evolves such as 

Abomasnow

Absol

Aggron

Tyranitar

or maybe Scizor incase he comes upon a Scizorite and that he likes to trade of his pokemon for Tracey's Scyther while it's wearing Metal Coat

or just get one of his Pokemon from Professor Oak incase he comes upon one of the Mega Stones that work for them
