No need to apologise, and you didn't sound disparaging! The discussions so far have been interesting in showing me what people expect when they see cards used in a game - and as with any expectations, I deviate from them at my peril :) I decided to explain at length because it helps me visualise things; sorry, I used you to think out loud!
This shows that we need to think about how we use cards, and how we explain their use - it may well remain just what it is, of course, but if it does it will be deliberate.
