Affinity wants to flood the board with cheap artifact creatures like Pinnacle Emissary and Kappa Cannoneer, backed by Mox Opal and Urza's Saga for mana acceleration; Wrath of the Skies is an excellent sweeper that can wipe their whole low-cost artifact board for a modest energy investment. Consign to Memory counters colorless spells and triggered abilities outright, hitting cheap colorless threats and value triggers like Kappa Cannoneer's trigger ('Whenever this creature or another artifact you control enters...') or Weapons Manufacturing's Munitions creation. Faithful Mending and Persist are too slow against this hyper-aggressive artifact swarm, so prioritize sweeping and countering their board development instead.
