Deadly Cover-Up
Sorcery
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.

If you can't exile enough cards to meet or exceed the required mana value, you can't choose to collect evidence at all.

Unlike many other effects of this kind, Deadly Cover-Up allows its controller to exile a basic land.

Once you've announced that you're casting a spell, players can't take actions until you've finished doing so. Notably, opponents can't try to remove cards from your graveyard to stop you from collecting evidence.
