I actually don't mind the Mass Hysteria . But I think the Bloodhall Ooze has very little upside in this type of deck. I would add another copy of Lightning Bolt and a couple Goblin Guide

You might consider Dryad Militant or Firedrinker Satyr instead of Tattermunge Maniac , because they don't have to attack each turn and have an ability that could be useful in some situations. I'm more of a fan of Dryad Militant because it doesn't drain your health, but fire-breathing can be nice.

drop Elvish Visionary and Dryad Sophisticate for more burn. Those are way too slow for this deck

xlaleclx- I believe the reason for the Visionary is for the refueling this kind of full on 1 drop aggro deck desperately needs, and the Sophisticate is pretty much a two mana two power unblockable in modern.

neither are very good in this deck.
