Deadly Cover-Up — Murders at Karlov Manor #83

As an additional cost to cast this spell, you may collect evidence 6.

Destroy all creatures. If evidence was collected, exile a card from an opponent's graveyard. Then search its owner's graveyard, hand, and library for any number of cards with that name and exile them. That player shuffles, then draws a card for each card exiled from their hand this way.
