The word deliberate should be removed.
Black cards should be used to stop opponents gaining an advantage from coughing up a "cute" free. The overwhelming majority of these instances are "lazy" fouls that kill momentum before it starts, or else trips designed to stop an attacker reaching a shooting position.
It's extremely difficult to judge these incidents when they involve a head-on tackle, as in many of these cases the foul is caused by trickery and movement, rather than a purposeful attempt to kill play by any means necessary.
Instead we should concentrate on fouls from behind.
So something along the lines of this would suffice:
"when tackling a player from behind (i.e. at an angle between 90 and 270 degrees from the direction of the attacker's movement), if the tackling action results in a technical foul that causes the ball carrier to trip or stumble, the tackler should be punished with a black card."
Simply put, if you choose to tackle a player from begin, don't foul him, or it's an early bath.
