Once Oblivious Bookworm's ability begins to resolve, it's too late to put any permanents onto the battlefield face down under your control or turn any permanents face up to prevent yourself from having to discard a card if you choose to draw a card
That means you lose that creature the turn you put this Aura onto the battlefield, and then lose it for the next four turns as well (three turns to remove the counters, and one to sacrifice the Cocoon the creature is still tapped that turn)
And whenever you journey through the waste, you'll find Junk that can be turned into more useful cards
If you control more than one creature with "This creature can't attack or block alone" they can attack or block together, even if no other creatures attack or block
The Zidane promo, sadly, wont add any real value to the purchase
As it is a class or job type, youll find it stapled onto Humans, Angels, Kor, and even Elephants
