My pre-pull prep on trash goes: SS on tank, Adlo on tank, eye for an eye, rouse, virus the hardest hitter after tank pulls, CS, swiftcast -> shadowflare, dots, bane and broil spam, refresh dots, rebane and just maintain. If I know everyone is going to be taking damage I drop deployment tactics pre-pull as well. Scholar cooldowns have relatively short recast times so you can normally cycle available cds as they come back up. As someone previously noted, lustrate should be used pretty often but don't be afraid to stack lustrates before huge pulls.
