The Mindskinner can’t be blocked.
If a source you control would deal damage to an opponent, prevent that damage and each opponent mills that many cards.
It slices away the most precious memories first, then the mundane, until all that remains is blank, formless fear.
If you somehow control more than one of The Mindskinner, the multiple replacement effects will have no effect. Damage dealt to an opponent by a source you control will be replaced only once with that opponent milling that many cards.
Random a card of Magic: The Gathering (MTG), but you can also roll the D20 dice, random a Planeswalker, have fun with the random rules and more.
