Whenever a creature you control dies, you may search your library for a creature card with lesser mana value, put it onto the battlefield tapped, then shuffle. Do this only once during each of your turns.

Mind's Contagion has haste as long as there are two or more creature cards in your graveyard.
Whenever Mind's Contagion deals combat damage to a player, until your next turn, it gains “Noncreature spells opponents cast cost an additional 2 life to cast.”

As Scion of Silence enters, choose a nonland card name.
Other permanents with the chosen name lose all abilities.
