Gift of Perfection

Sorcery

Each opponent reveals cards from the top of their library until they reveal a creature card. Assimilate one of the creature cards revealed this way. Then each opponent puts the other cards they revealed this way on the bottom of their library in a random order. (To assimilate a card, put it onto the battlefield under your control with a +1/+1 counter. It's a Borg artifact creature and loses all other creature types.)
