The fact that this signature hasn't been reviewed in nearly ten years says quite a lot about it, I think. First, I'll highlight the good: It has some good icons. +2 to Will or Fight, +3 to Book or Foot, you can definitely use this card to help pass some important tests, or even to increase the odds of oversuccess, a Rogue staple.

But it's not a skill card, it's an event card. It's a cheap one, and it's fast, but its power is... not great. Compared to Trish's signature, Skids does not automatically disengage from anything, nor can he stop enemies from engaging with him. This means that if Skids is getting overwhelmed by enemies for some reason, this signature only delays being hit by them a round. That's still not without value (you could play this to cancel the Retaliate/Alert keyword, for example... but only in non-Elite enemies), but it makes the signature very conditional in its use. Furthermore, where Trish can proceed to move through a Monster-infested room, Skids will continue to engage anything in any new room he enters. This card's effect has some value, but it's just too situational. You could easily go a whole campaign without needing it, but rarely will you get through a scenario without ever thinking to yourself, "I wish I had just a couple more icons for this test".

So you basically might as well treat this as a slightly better Unexpected Courage. That's a fine concept in a lot of cases, but not for a signature card. Unless for some reason the various Rogue economy cards are unavailable to you, Skids will play much better with the advanced versions of his signatures instead.
