You have posted the same poke in spot 1st and 4th.
Anyway, the first poke is HP bug, making it a poke worth max 2mils even with 31 speed.
The second is HP ground which is very good but not the best, also it's 26 speed is a hinderance. Serperior needs 27+ speed and +speed nature atleast to outspeed some dominant meta pokes like Tornadus and Thundurus. Therefore i can project a price of around 3 mils for this one.
The third is HP rock, again a good hidden power but far behind the usability of HP fire or even ground. The only use would be to hit Togekiss and some pokes like Charizard, but that's it. Also 26speed is not so nice so i can say around 2.5mils.
