i don't think absol is a legendary in the game but it is in the show
No Shaymin is not a legendary for several reasons, firstly it has appeared in many Pokemon movies/episodes with more than one of them. Secondly it is like Zoroark, Zorua, Phione and lucario these are all just rare pokemon!
It is a rare pokemon, but it is not a legendary pokemon

It is very unlikely for Pokemon to not show reruns, for it's just to buy more time to create new episodes. Just be patient and the new episodes will come shortly.

The legendary is palkia
Noivern is not a Legendary Pokemon.
