My players don't like the 5MWD, but they like having interesting things to do every round of combat. In 4E this was pretty easily accomplished, since even At-Wills did a little something special.
But in pure attrition models, conserving your resources often means not doing something...
If you feel comfortable, record the training session you run. It doesn't have to be top quality, but you can go the extra mile to really demonstrate how everything works, your reasoning behind things, AND have a nifty video both you and they can show to future people they might need to train.
My favorite was Snow White as a vampire, eventually defeated and sealed away by dwarven champions in a cottage in the darkest wood. I later discovered Neil Gaiman wrote a similar short story, so I was happy as a clam.
We've been running it that way for decades. More than one noble knight has brought the King's Daughter back from being a vampire bride! It's the (expensive) happy ending to stories involving innocent people cursed to undeath.
The mighty d20 itself is a bigger threat to bounded accuracy. Even a level 20 with +5 attribute and expertise can potentially contribute less than the mighty d20, and the d20 is available at 1st level!
I do want to go on record that Black Spider is an absolutely ridiculous name for a drow. It's like calling yourself Drow Drow McDrowface.
Much better if the name has no initial connection to drow, and was taken over by a drow with a sense of comedic irony.
"I heard someone using the name and...
I would do it IN REVERSE. Gundren Rockseeker was once the Black Spider/Dread Pirate Roberts, but someone came in and pulled a Xanathar on him and took over his operation, legacy, and even his name!
It allows Gundren to be a justifiably weaker, uses the DPR themes you are interested in, and...
I should clarify. When the zombie/skeleton is defeated, I count the remains as both a humanoid body and an undead body. My game has been improved by this ruling.
Of course, sometimes the remains are heavily damaged and require mending (the spell, physical repair, or both). It's case by case.
