A very important card for true solo Protection players; not quite as big a deal as as Under Surveillance in Justice, but close. Previously, the only non-character-specific ways to stay safe from the "what if Rhino draws an Advance?" problem when flipping down in Protection were a single confusion from Professor X and having the Black Widow ally in play. Ready for a Fight gives you three more safe flipdowns per deck cycle, which is enough to satisfy heroes who like to go alter ego frequently but not necessarily flip every single turn (e.g. Groot, She-Hulk).
The biggest beneficiary is of course Black Widow (hero this time), as she can loop these every turn with Safe House #29 - and greatly prefers being in hero form when encounter cards are drawn so she can trigger her other preparations. Once the loop is in play and you're flipping every turn, the experience is a bit like playing the Psylocke->Danger Room-> Professor X combo, except you're using other Protection cards to negate or blunt the villain's attack instead of confusing them. That may not sound amazing but hey, it can't be negated by Stalwart!
Now we just need a 3-of 'fixed' variant of Not my Responsibility in Aggression (maybe drop the ally clause?) and a non-trait-locked version of Tempus in Leadership...
