CMV, a yellow card during in a football game should be followed by a 10 minutes suspension.

Having a yellow card during a soccer game has almost no impact on the game. In my opinion, the rules and the fact that there was no VAR until now encourages situations in which players will fake an injury (yes, I just saw Mbappé faking) to get a free kick. The only result, if the player is caught red handed as Mbappé was, is at worst a yellow card and the game will go on. It is also true for rough plays on certain players (for example, Griezmann has been a target during the whole game against Argentina, and except for one yellow card, there was almost no  punishment).

Having a 10 minutes suspension like in rugby would really penalize the whole team which would need to run more and get tired faster. This would really discourage foul plays and would both protect the players and their health from tough plays and eliminate the aspect of soccer that every afficionado hates: simulation.

Yellow cards are a warning. Red are the ones that come with punishments. Your recommendation basically just eliminates yellow and turns them into red. 

As for faking injury, that should result in ejection from the game, not a penalty in time.
