Obliterator's Obliteration

As an additional cost to cast this card, discard a card named "Deception of Obliterator"
Choose a target land your opponent controls with at least 10 Obliteration counters on it. Each card adjacent to that land is exiled, each card adjacent to those exiled is destroyed, and each card adjacent to those destroyed is tapped, then gain control of the original land. Stacks of cards like graveyards and libraries count as a single card from top down perspective
