(1/25/2019) If the entering creature leaves the battlefield and returns while Guardian Project's ability is on the stack, that same card will be a new creature you control that shares a name with the creature that was on the battlefield, so you won't draw a card
This is more of an anti-control finisher, since when you're playing another control deck, not having control of the board generally means that you're outmatched with counterspells or removal spells

This doesnt have to be a combo more often than not its just a direction if the cards in your deck all point in the same direction that is to say all work to achieve the same goal, whether thats stockpile and use energy, mill them, give you a bunch of tokens and swarm or Craterhoof them or any number of ways to win, the deck is more effective than a jack of all trades, master of none approach and that was a seriously long run-on sentence, I apologize
