Bogles wins by stacking auras like Ethereal Armor, Rancor, and Armadillo Cloak on a single hexproof creature (Slippery Bogle, Gladecover Scout, Silhana Ledgewalker), so we need answers that don't require targeting. Drown in Sorrow's -2/-2 sweeps their 1-toughness hexproof creatures right off the board regardless of hexproof since it doesn't target, which is the single best answer to their whole gameplan. Tragic Slip similarly doesn't need to target through hexproof and its morbid -13/-13 kills even a fully-loaded bogle if anything has died that turn. Nested Shambler's small tokens don't meaningfully block a trampling, lifelinking Armadillo Cloak threat, so it's cut for these non-targeted sweepers.
