I only support this if they are fun decks that are not very strong competitively.
Such as Fractal Fate Eggs or Skeleton/RT.
A fun deck will encourage creativity more than a strong deck.
There are also disadvantages to posting a strong deck to the entire game, because then the world will see it and copy it.
Lastly, I think the creator's name should not be mentioned. Chances are another player will have already run into the same exact concept.
