Vendetta is a reasonable keep against stuff that isn't rogue if you think they'll care about the board (yes bomb hunter, no control warrior)
Academic Espionage is a bad card, but it’s fun 🙂
Tak Nozwhisker is a worse card, but it’s even more fun :)))
Don’t go in too hard on your first Spectral Cutlass if you think they might have weapon removal.
You can replace EVIL Miscreant and Edwin VanCleef with Pilfer and Underbelly Fence to be more on theme, but it will also be much much worse.
