4c HollowOne dumps its hand fast with Burning Inquiry and Faithless Looting to cheat out Hollow One and recur Vengevine, so graveyard disruption and a sweeper are premium. Nihil Spellbomb exiles their graveyard, denying Vengevine's recursion trigger before it can return. Toxic Deluge cleanly answers their small aggressive creatures like Blazing Rootwalla and Marauding Mako. Consign to Memory is efficient one-mana interaction that counters colorless spells like Hollow One and catches triggered abilities along the way. Force of Negation is weak since it can't target creature spells, which make up most of their threats, so we trim it along with Spell Snare, whose mana value 2 restriction misses most of their curve, for more proactive, cheap answers.
