How exactly do BFC's work?

The judge at my venue said that you can only use two BFC's during a three round tournament, and when you do play BFC's you can only play each one once. Is that right?

Also, I looked in the tournament rules and I couldn't find anything about it, so if I could be directed to the passage that explains this, it would be appreciated.

2.2 Battlefield Condition Cards
Battlefield Condition cards are tournament legal in WizKids-Sanctioned events. Battlefield Condition cards are optional for each player. An opposing player cannot stop a player from using Battlefield Condition cards. Each player may bring a number of Battlefield Condition cards equal to the number of rounds in the tournament minus one. None of these Battlefield Condition cards may be a duplicate. These Battlefield Condition cards make up a player’s “hand.” Other cards, such as Feats, must be added to the hand as placeholders so that the number of cards in your hand equals the number of rounds in the tournament. These extra cards may not be put into play for any reason – they serve as placeholder, “dummy” cards only.

After the battlefield is prepared (see page 11 of the DC HeroClix: Icons rulebook), each player chooses a card from his or her hand to use for the duration of the game. Both players reveal their cards at the same time. If a player does not wish to play a Battlefield Condition card during a round they may substitute their placeholder card instead when Battlefield Condition cards are revealed. A player who uses a placeholder card in this manner does not return it to their hand; they no longer have the option of using it in place of a Battlefield Condition card.

At the end of the round in which a Battlefield Condition card has been put into play, that Battlefield Condition card is removed from the Tournament, and cannot be used in successive rounds. After Battlefield Conditions are put in play, each player will note on their opponent’s team registration sheet which Battlefield Condition the opponent put in play that round. Future opponents may see the Battlefield Condition(s) which have already been played, but may not see those Battlefield Condition(s) that have not yet been played.

Yeah, the Judge got it right.

Okay, I trusted him, as he has judging a long time longer than I have been playin'.

But it's good to know.
