What old pokemon do you want in the unova dex?

Confirmed Oldies but Goldies:
Psyduck
Golduck
Riolu
Lucario
Beldum
Metang
Metagross
Larvitar
Pupitar
Tyranitar
Lapras
Arcanine

That's 12 pokemon. Counting Kyurem and its 2 formes as seperate pokemon, that's 135 more old pokemon (If the other event pokemon aren't in it) to go!
What Pokemon do you want to see returning to the series?
Also, I reckon Larvitar and Beldum will be found in the desert area and lapras will be in the Abyssal ruins as a boss maybe???

Discuss.
