Reality Engine

When Reality Engine enters the battlefield,
Commit any number of cards from your hand.
For each card Committed this way, put a reality
counter on target permanent. (Exile the
Committed cards until this card leaves the battlefield.
When it does, shuffle them into your library.)
Each permanent with a reality counter on it is
Adamant. (Spells and abilities cannot move it from
the battlefield to zones other than the graveyard.)
