Err.. Team life took only 51 cards and no penalty issued.
I see your point, suxerz. We could've included the text "up to." That wasn't the intention of the card and it's hard to prepare for every possibility. With regard to Team Life, they made a mistake and it seems a little crazy to penalize a team for penalizing themselves.
Since the 60-card bonus occurred before seeding it'd be pretty difficult for a team to "game" their next round vault to reduce the number of matches they'll play.
