I don't know anything about the above pokemon, so I can't say whether there's a trait_connection or not.

Edit:

After knowing the pokemon thanks to the taggers, I think the following are the trait connections:

• pillars
• serpents

Conkeldurr and Kanako lug pillars around, and I guess Rayquaza's a big ol' snake (god?).

Also biggest reasoning that raquaza and kankos elements are Sky.
