Mary's Outrage

This spell cannot be countered.
Exile an artifact you don't control, then
Proliferate. You may search your Library,
Graveyard and/or hand for a card named Mary,
Envious Cyberkin, show it to your opponent,
then put it on the battlefield for free. Then,
shuffle your library.
A shrill scream echoed throughout the Grid, piercing
the calm of the city.
