Rest in Peace exiles cards instead of letting them reach the graveyard, which denies Enduring Curiosity its return as an enchantment and shrinks Yuriko's graveyard count. Sheltered by Ghosts both protects a key threat with ward and lifelink and exiles one of their blockers or value creatures like Dream Beavers or Spyglass Siren for as long as the Aura stays on the battlefield. Smaug and Twinmaw Stormbrood are the cuts since they are among the more expensive plays and are easily answered by Bitter Triumph, Shoot the Sheriff, Floodpits Drowner's tap and stun, or a We Say Thee Nay counter. Erode trims as a lower-impact removal spell against a deck full of small bodies that Burst Lightning already handles. The full land count stays untouched to keep hitting four- and five-mana plays on time.
