Deeprealm Mechonoid

Whenever a spell or ability an opponent controls causes that player to discard cards or to mill or
exile cards from his or her library, put that many
charge counters on Deeprealm Mechonoid.
If a player has less than 80 cards in library, you
may remove all counters from Deeprealm
Mechonoid. If you do, Deeprealm Mechonoid
deals to that player that much damage, halved
and rounded up.
