Tranquility Pilgrim

When Tranquility Pilgrim enters the battlefield,
you may discard any number of cards. If you do,
for each card discarded this way, put a card that
shares a card type with it into your hand from
your graveyard.
The oppressive majesty of the Tranquility is too much
for most humanoids to bear. To live here, you must be
prepared to lose as much as you wish to gain.
