If you have issues with board wipes, try throwing in something like Dictate of Erebos so they suffer too, and maybe some graveyard recursion (I'm not sure what recursion is still legal in standard)

Take out the whip, ulcerates and what not.... you NEED Thoughtseize to avoid losing all your guys to a well placed Anger of the Gods or End Hostilities

Thoughtseize will allow you to get those annoying board wipes or high cost creatures out of the way.

Also Its probably best to stick with 60 cards in your deck.

could splash blue for Negate against sweepers. situational, but might be worth it. could go along with running Ordeal of Thassa , allowing for bigger impact creatures and enabling you to take out Pain Seer if you'd like.

If you can't afford Thoughtseize , you can use Brain Maggot or Despise . I think Ruthless Ripper and maybe (but probably not) Grim Haruspex are too slow for aggro. It's probably a good idea to go up to 4 copies of Herald of Torment . Something else you might want to consider is splashing white for Sorin, Solemn Visitor , Athreos, God of Passage , or Ajani Steadfast .

For board wipes, I would consider splashing in white for Athreos, God of Passage that way when they wipe with Anger of the Gods, Drown in Sorrow or End Hostilities, They have to pay 3 life for each creature to make sure they STAY in the graveyard.

Oh and with white you can also add in Sorin, Solemn Visitor and Utter End ;)
