Deadlift: 5 rounds for max reps at 50% of your 1 rep max. During each rep you will pause for 4 seconds at the top of each deadlift, lower the weight, and repeat. There is no dropping unless your grip gives out.
If you complete 20+ reps, keep the weight the same, but on the next set add an extra second to the hold at the top. For example, if in the first round you complete 22 deadlifts, wait 2-3 minutes and go for another set of max reps holding for a 5 count at the top, if you complete more than 20 or if you feel the set was not challenging enough, add another second and so on.
