Analyze the Pollen (Promo Pack) [Murders at Karlov Manor Promos]

As an additional cost to cast this spell, you may collect evidence 8. (Exile cards with total mana value 8 or greater from your graveyard.)

Search your library for a basic land card. If evidence was collected, instead search your library for a creature or land card. Reveal that card, put it into your hand, then shuffle.
