100% against this. Absolutely not necessary and bad for the game. Punishing skilled players for winning with weaker cards is not the way to do it.

The ghost card punishment is already doing what this does but much better.

On top of that, some cards are better at a lower level, on certain rule sets, especially reverse speed. I only have a level 1 Sand Worm and I get to use it in Gold when it's reverse speed.
