Levia, Child of Envy

Polymorphine — When Levia, Child of Envy
enters the battlefield it enters as a copy of any creature on the battlefield, except it has "When
this creature enters the battlefield, destroy other creatures with the same name as this creature."
Whenever Levia, Child of Envy deals combat
damage to a player, you may look at that player's
hand. If you do, you may cast a spell from among
those cards without paying its mana cost.
