This becomes kinda decent after your second ready on a turn. Still +2 THW per 2ER is bad, if it werent because you can store the effect in the field for later turns. Therefore, it becomes a wild +1 bonus for when you need to score a clear for things like Making an Entrance.

At the third hero ready, its on the average +3 THW per 2ER.

Problem is, there are quite few heroes and cards that can reliably ready enough to collect 2-3 readies for this card. And it has to compete with other better alternatives that does not lock your hero's basic action (like Surveillance Team or Beat Cop)
