Returning to Aggro

I want to get back into magic over my winter break, but I am kinda burnt out of playing tron. I want to play an aggro deck and am looking for advice on how to use some of the cards I already have to build an aggro deck. I feel more comfortable with aggro decks and have shells of a goblin deck and jund death's shadow deck I used to play. I really don't want to spend more than $50 on new cards since I only play mtg when I am on break from school. Does anyone have advice on what I should do? I have my two lists posted below. I want to either use pieces from my old deaths shadow deck and make it more aggressive (maybe moving away from deaths shadow since I am not great at piloting the deck) or just upgrading my aggro goblins deck (I prefer to not play combo goblins). Thanks for the help!
