$1556 cards in a tuck box
Every marking must be able to be either the most important thing or invisible, no matter which elements you're using. These cards carefully balance whitespace and layout so that elements are placed in optimal locations for how they're likely to be used and so that no other elements conflict with them in terms of style or location. The pips have an increasing visual weight so that low cards are intuitively distinguishable from high cards. The varied designs ensure that you never mix up a 6 for a 7. Visual separation and center placement of the 1-36 numbers ensure that you never mistake the 7 of hearts for a value 7 card.
