If you want to check it real fast just use Ctrl+F and type the Pokemon's name.

Answer 2

Yes, but only by transferring.

Buneary and Cottonee were available in Dream World in Gen V. Serene Grace Deerling was given to you by a scientist on Route 6 (in the lab) in B2W2.

Otherwise, the Friend Safaris don't have those 3 Pokemon.

EDIT: whoops Sawsbuck is there; so breed that for a Serene Grace Deerling.

Answer 3

Buneary: Transfer through Pokebank
Cottonee: Transfer through Pokebank
Deerling: By breeding HA Sawsbuck from Friend Safari or transfer through Pokebank
