Hi there! 

Sometimes you need tiny speed adjustments between NM and UNM. I have built I think it was a Batman Saladeater comp during a takeover and had to tweak a lore of steel to get it to run correctly in both NM and UNM. The difference was 0.19 speed for a single champ.

That said, it looks like those champs ARE still protected on turn 3, 5, 6, 8, 9, and 11. I would be leery of Ninja messing it up in the actual runs though. His speeds are tricky tricky. Do you have a gravechill or coffin smasher or someone else you could toss in there in his place and test out if it's Ninja messing up the block damage? Cause it certainly looks to me like block damage still should be in effect when the CB goes.

Did you make sure to calculat eyour true speed ? when you click on teh speed field you get additional buttons and dropboxes to mention how many speed/perception sets you're using and if you're using lore of steel or not. As HarleQuinn mentionned tiny variations of speed can derail the whoel comp and those are usually due to true speed not being calculated properly.  Other than that I suggest to check out DwJ's discord and ask teh question there, you'll find plenty of quick and precise answers to your questions.
