The main idea is to leverage human ETB triggers with Thalia's Lieutenant until I get Zada, Hedron Grinder into play, Then, the idea is to target Zada with one of the pump spells to make my entire line bigger (possibly creating some tokens at the same time if I have an Equipment on the board, or giving my creatures trample). Using Zada with Expedite would give me lots of card draw, too.

The Sideboard section is initially being used as a "maybe board" for deck building purposes.
