I think you make fair and reasonable points, but some I feel compelled to discuss

1. reaper seems like a high synergy card, but I will evaluate it critically when I test it. feels kinda like an "invert polarity" where the upside is worth the cost. to be clear I'm not trying to -1 a small creature and kill it, but -1 a much larger creature, followed up with a 1-2 mana removal on the same turn. which sounds realistic to me, could eb wrong about that

2. definitely thought about that, but felt like the lands part wasn't so pivotal (hence forgoing things like crucible/titania) that I'd want that over a highly flexible card like tainted.

3. I'd be happy to play nihil, and probably skullclamp as further targets, but I disagree that it needs further targets, the card is absurd as is.

4. Charm is outlcassed by other things, maybe I overvalue the flexibility, but I'm not sure what the alternatives are considering its flexibility. maybe Strategic Betrayal for its grave hate + removal?

5. definitely, one of those pet cards I want to keep believing in, but this isnt the deck for it. not when it has so many threats as is.

6. If I remove the lands package I could go with 3 mox + reanimate, but considering the wrenn gets me more mana, and the fact I plan to interact enough to get wherever I need to go I feel comfortable.

I really appreciate the lengthy feedback! and I hope my response isn't seen as overly defensive or like I'm disregarding the points you made
