Deadlifts should be heavy – if you are scaling, then aim for about 70% of your 1RM. These do not need to be strung together. Toes-through-rings are like toes-to-bar except you’ll probably find them easier. If you need to scale, do V-ups. Since this is a longer AMRAP, most people should aim to do 25 double unders instead of scaling the number back. (gotta get used to those higher sets at some point!)

AMRAP in 20 minutes:
5 deadlifts, 275/185#
15 toes-through-rings
25 double unders
