Evernight's
>When there are X or more Remembrance units in the team
is pretty lenient as long as you run 3. Most people thought you'd be forced to run 4 Memosprites with Evernight, but losing on 10% Crit DMG isn't that big of a deal. They really want you to run at least 3 Remembrance units with her, but allow some flexibility in her teambuilding.
