These are the Pokemon we've called Ash's reserves (despite us knowing that he sends the starters to juniper from BW050)
And yes I do count Scraggy as a reserve, he may be the most developed but his appearance count is still way low with up to 12 episodes difference.
Indeed Scraggy, along with Tranquill and Palpitoad have a second class appearance rate to the starters and both Swadloon and Roggenrola/Boldore can easily be forrgotten, but who is the best character? Who has the most potential?
And if Ash was going to have only 6 Pokemon this series as usual, which two of these would you like him to have alongside Pikachu, Oshawott, Tepig and Snivy?
