Amass the Vampire Legion

Amass 3. (Put 3 +1/+1 counters on an Army
you control. If you don't control one, create a 0 /0 black Zombie Army creature token first.)
Then, the Army you amassed explores. (Reveal the top card of your library. Put that
card into your hand if it's a land. Otherwise, put a +1/+1 counter on the Army you amassed, then
put the card back on top or into your graveyard.)
