Rule 120.2b
Official source text from the 1 May 2013 Rules release
If an effect instructs more than one player to draw cards in a game that's using the shared team turns option (such as a Two-Headed Giant game), first each player on the active team, in whatever order that team likes, performs his or her draws, then each player on each nonactive team in turn order does the same.
