Confused?
The card text here basically boils down to: Attempt nearly any test you're normally bad at, with a +2 advantage.
4 Difficulty treachery hitting your Silas Marsh? Guts + Rise to the Occasion for a total advantage of +4!
4 Difficulty test for Ashcan? Commit Rise to the Occasion + Perception for a total advantage of +4!
3 Difficulty test for Wendy? Rise to the Occasion + Baseball Bat for a total advantage of +4!
Even if you cut out all those other cards, Rise to the Occasion still lets you attempt tests you're normally bad at with a +2 advantage, this is most important for those forced scenario tests and unique treacheries that just gotta go, I speak off the Locked Door, Frozen in Fear, that kind of stuff.
In my opinion this card is alright by me, and downright great in a Silas Marsh deck.
