If the noobs (or anyone for that matter) can lock the URs as soon as they pull it, then the spamming of trades should stop or drop, cause they wouldn't be able to find the card in the deck. But I don't think a lot of new guys would know about the lock feature yet.

At most, they would just get annoying cheers.
