Their deck leans heavily on triggered abilities (Phelia, Flickerwisp, Ephemerate blink triggers) and cheap creature spells, so Consign to Memory is well positioned to strip value off their blink engine. Stern Scolding cleanly answers Orcish Bowmasters and other small-bodied threats before they generate value. Spell Snare whiffs on most of their key cards since Thoughtseize, Solitude (evoked for free), and their creatures don't line up well at mana value 2, and Spell Pierce is weak against a deck with plenty of mana up. We keep our proactive plan largely intact since we're the beatdown here.
