Alright, so I'm looking to add a little more choice discard. I'm looking most likely at Blackmail, although Despise and Duress are options too. I'm not entirely sure what to take out. I'm leaning towards Funeral Charm, but could also end up dropping Waste Not, as it hasn't really been performing all that well. Any thoughts?

I was unimpressed with Waste Not in modern as well, I dropped it and added Bump in the Night instead. Although, I haven't taken it to a tourney since for playtesting yet. I also run Funeral Charms, which I likey a lot!

-1 Waste Not +1 Rakdos's Return

I Love Rakdos's Return! I agree!

Rakdos's Return is too slow for modern, especially for a deck like this that runs so few lands. I'm not really a fan of Bump in the Night, its just too overcosted for what it does. And neither of them really solves my issue, which is trying to find more choice discard besides just Inquisition of Kozilek and Thoughtseize.

yeah, Despise and Duress are the next best options obviously, I just figure that a one mana for 3 damage spell, like Bump in the Night is almost as good as a Lightning Bolt, and if you could possibly play it again later, than all the better? I dunno....What about running Magma Jet?? It helps dig for your discard spells, and can also deal with pesky stuff like Goblin Guide ?

What would I drop for Magma Jet though? I don't think it's better than anything I'm currently running.

Coukd try Blightning since its a deal 3 damage discard 2 and also consider that red gives you the most recrnt chandra acting as a free draw engine for you if you think the deck can handle her as 2 of. Maybe want to consider Distress as its two black and can remove anything Thoughtseize would

I'm already running 3 Blightning and I definitely think Blackmail is better than Distress.
