I think Rita is super fun. Her Survivor mixed with tricks just keep getting better. Her signature has always been incredibly lacklustre except in rather niche applications, and even still, I think Rita's signature just doesn't do anything at 1 player, and at 2 player it can act as a fast action engage to get an enemy off your cluever. But after Edge of the Earth, The Scarlet Keys, there are some really interesting interactions with this signature that make Rita a 3p or 4p powerhouse AoE dealer. Now, this is a heavy caveat, because you still need to have the tools in hand, and without search, and minimal card draw, being setup at the time you need to pull this off is rather unlikely to happen.
This card comboes super well with newer cards that have added automatic evades to their effect. Sweeping Kick now becomes a 3 damage event. Breaking and Entering is now gain a clue and deal a damage. Confound is discover 2 clues and deal a damage. This isn't earth shattering of course, but important to consider instead of simply throwing this card at a skill test. Dirty Fighting now becomes essentially a free 1 damage as that evade gives you a free fight action. This is on top of Rita's innate 1 damage ability, assuming you haven't drawn an eldersign. But what if you could evade all enemies in one action? Survival Instinct (2) is something else. 1 evade actions turns into dealing 1 damage to everything at your location?! Great.
Obviously, this is all so situational. The main benefit of course, is Rita being able to use her agility value to ping damage. It is most effective with swarming enemies, and just higher player counts when there are simply more enemies. In a way, this space is also occupied by the Hemlock Vale card Elaborate Distraction, which simply lets you ping every enemy at your location and adjacent locations. And it leaves me feeling I wish Rita's signature had the option to also engage enemies at adjacent locations, because now this also feels a little underpowered.
Ultimately this card is still well underpowered for a signature, and extremely niche, and will get almost no value in true solo (though a free engage on an aloof enemy is still very nice). This card does not affect Rita's playstyle because you cannot play around the hopes of getting it. But on average, when combined with Rita's actual signature Sweeping Kick, this card reads as a fast, 0 cost engage action and 1 testless damage. Its not amazing, but when combined with Long Shot, Rita now does have some extra ways to deal ping damage.
