1) GTFO (use blink, force staff, glimmer, drum etc)
2) ♥♥♥♥ EM UP (seriously just throw everything you have at them)
3) FARM ... wait that doesn't need caps, farm, keep your skills off cool down, you just tea bagged them from the sky don't worry, they leave the lane now no questions asked.

Low cooldown, low mana cost (offset by shakers low mana pool though. Aghs will now wreck from a distance, from any angle, and when they least expect it...or when they most expect it, whatever.

Mana boots early, If you aren't snowballing take the new movespeed windlace and build it into drums for mad setup plays.

Always know your exit, remember, you are gonna GTFO or ♥♥♥♥ EM UP, farming is just a different angle on those two situations, if you can't find the gold for the core items don't worry, they are expensive as ♥♥♥♥ and you are still an Earthshaker, stack some camps get some gold and pick something within your budget that enables you to farm enemy faces!
