I've played both approaches, fow and deafening silence. Silence seems better against combo, but having fow increases by a lot our blue matchup. Played the playoffs with BUG survival and got 4-2 (9th place -.-) , fow helped a lot more than FoV would have.
Seems like there are less combo out there and I don't think it's worth playing white for it. 4 Leovolds between maindeck and sb seemed pretty good too. Too much blue out there, and with fow leo is a house.
