Actually, its not the only one, because the deck needed other tools as well, but this in conjunction with Card not found, Card not found and Card not found was a pretty good base for a deck
Players constantly complained about the cards they had lost, and others played Millstone because it was card advantage - completely missing what that term actually means
My verdict: A stylish, protective deck box thats ideal for collectors and Commander fans who want to store, protect, and showcase their cards in one elegant case
Just like that card, the end-of-turn blinking is a great way to accrue value by blinking permanents with strong enters triggers
I feel in Battlecruiser you shouldnt have a permanent advantage that enables your commander to operate with zero downsides whatsoever before anyone has even taken their turn, so Im not adding Leyline of Anticipation
