To my knowledge of the rules and the page on Buddies

"At the start of the game, each player chooses 1 monster from his/her deck and places it into the buddy zone, then that monster (and all other cards with the same name) will be his/her buddy during that game."

However, cards in a deck can only be played if the flag card says they can.

The official ruling regarding cards not of the flag but in the deck says

"You may put cards that are not allowed by your flag card in your deck. However, they cannot be played on the field. Cards not allowed by the player's flag loses all information on it, as if it were a "blank card". Also, if they enter the field due to any ability, they will be sent to the drop zone."
