Who will Ash's final party member be?

[UltimatePokemonExpert]

So with the latest episode that aired in Japan, we know that Ash now has a Goomy. It occurred to me today that up until Kalos, Ash has, without fail, always caught the Grass type starter and therefore has never caught a Grass tupe Pokémon that wasn't his starter, (Other than Leavanny which is part Bug). However, since he chose a Water type this time around, he now has no Grass type like usual and has only one space left in his party. It doesn't seem like he'll be catching more than 5 or 6 in Kalos, so we can conclude that he'll either break the trend of always having at least one Grass type on his team and catch another type of Pokémon, or he'll keep with the trend and his last member will most likely be either Phantump or Skiddo, since they're the only two base form Grass type Pokémon from Kalos other than Chespin and Pumpkaboo which are already owned by other main cast members. Anyways, I want to know what you guys think- which Pokémon will fill that final party slot?

It occurred to me today that up until Kalos, Ash has, without fail, always caught the Grass type starter and therefore has never caught a non-starter Grass type without also catching the Grass type starter. However, since he chose a Water type this time around, he now has no Grass type like usual and has only one space left in his party. It doesn't seem like he'll be catching more than 5 or 6 in Kalos, so we can conclude that he'll either break the trend of always having at least one Grass type on his team and catch another type of Pokémon, or he'll keep with the trend and his last member will most likely be either Phathump or Skiddo, since they're the only two base form Grass type Pokémon from Kalos other than Chespin and Pumpkaboo which are already owned by other main cast members.

You know this will end up getting closed and moved to the regular Pokemon Speculation Thread.

As to your theory, that no non-starter Grass type has ever been caught by Ash, Leavanny says hi to you.

I actually realized the Leavanny thing while posting so I went back and edited. Also, I apologize if I put this in the wrong place, its late and I'm not thinking straight.
