Personally I would leave the black card alone & work on the implementation of the card instead.
There is so much cod acting going on in football at the moment that no system will ever be perfect, the ref would need six pairs of eyes.
The one change I would bring in would be to total up yellow cards so that two or three cards would lead to a suspension. As things stand the yellow card is ineffective & something needs to be done to give it teeth.
Passing down suspensions for accumulating yellow cards would be unfair on sides who have to play more games than some other teams. A player can try to play the game in a fair manner but still pick up a yellow for mistimed shoulders, unintentional high tackles etc, I don't think there is a need to suspend a player for a few of them in a season.
Replying To SamandLiamSoon: "A bit of balls is all the black card needs. While I hate to compare our beautiful games to those of the foreign ilk it does pay to keep an eye how they run things. The English premier league and their decision to implement punishments for verbal abuse, surrounding a referee, looking sideways at a referee and it's enforcement was something that impressed me. It was enforced across the board by the refs and within a few weeks they had more or less stamped it out. And in regards to the stuff happening in penalty boxes at frees and corners they have improved that area too if not 100% perfect. Refs just need to have a chat with themselves and say enough is enough whether a junior d league match or an All Ireland final a black will be a black. They stay strong on this long enough it will work. But as long as a player thinks there is some chance they will get away with it they will continue to chance anything they can to get an advantage. Such is human nature. I think the first black card I saw was in an All Ireland club final and a Castlebar lad was black carded inside a few minutes. If that trend had continued we wouldn't be harping on about it now. It would just be another part of our game."
Consistency, or the lack of it, is the real problem with black cards. If a player was sent off by the referee for a black card offence, it would send a message to players and team managers. A bit of balls is required, as posted earlier. Second time sending this post.
