When this is blocked, you may pay {b}, and if
you do, put a +2/+0 counter on this creature.
When Frowning Gaper dies, you may discard a

"When nobody is nearby, they stand perfectly still, as
if corpses in death's sweet embrace. But a single sound
will send them groaning from their dreamless sleep."
