I don't think you have the definition of sucker effects correct. Generally, sucker effects are effects where the audience is led to believe something that isn't true. A common theme in sucker effects is make the audience think they know the method but then end in a way that disproves that method (sucka!). Another theme is effects where the audience thinks something and then is proven wrong (a monte type routine).
What you are referring to is the "magician in trouble" plot. First off, never use that plot as a first effect. You need to establish your credibility in the eyes of the audience first. Also, you can play the oops off as "wouldn't it be impressive if the top card was your card? Yeah, it would be but that never works." Then turn it over and show a different card. "Here is where the magic begins... "and then do the change. That might work better with your character and gives the audience a similar experience of building excitement (that would be cool), let down (it never works and the reveal) and then a second build up (here is where the magic begins) and the finale (reveal of the correct card).
Perception of reality is a selection of reality which results in a distortion of reality.
