With the new card Bruvac, the Grandiloquent, and the reformatting of mill as a keyword, I have a couple questions.
It specifically defines "if an opponent would mill one or more cards." Are they errataing things such as Tome Scour, which is clearly "mill?"
In the case that they are errataing, what about cards that are a little more unclear? For example, Tunnel Vision reads "If it is, that player puts the rest of the revealed cards into his graveyard." Because this does not directly read "puts the top N cards of their library into their graveyard," does that mean this is not "mill," and won't be affected by Bruvac?
