4c HollowOne fills its graveyard with Burning Inquiry and Faithless Looting to cheat Hollow One and Vengevine into play cheaply, so Nihil Spellbomb is excellent — exiling their graveyard strips back Vengevine's graveyard-return trigger and stops flashback and escape value. Damnation is a strong sweeper since their whole plan is small, cheap bodies (Nethergoyf, Psychic Frog, Marauding Mako) plus Vengevine and Hollow One, none of which survive a board wipe. We cut cards that don't pressure their graveyard plan or clear their board, keeping Thoughtseize in to strip a key piece like Hollow One before it hits play for free. Watch their discard enablers — Faithless Looting and Burning Inquiry fill the yard fast, so deploy Nihil Spellbomb proactively rather than waiting.
