Using single character variable names is always bad practice
Except
iright? Something likecounterorindexseems unconventional and unnecessarily verboseYeah, but it's easy to overuse it. If your for loop is much longer. For a few lines I'd agree, don't bother using something longer.
Code should scream out it's intent for the reader to see. It's why you are doing something that needs to be communicated, not what you are doing. "i", "counter" or "index" all scream out what you are doing, not why. This is more important than the name being short (but for equal explanations of intent, go with the shorter name). The for loop does that already.
If you can't do that, be more precise. At the least make it "cardIndex", or "searchIndex". It makes it easier to connect the dots.
