It's generally considered average since you can use this skill with any deck, but there are always better skills that can be used, ones that can fit better with the deck themes to boost it's potential.
But if your opponent has an Ojama, silent deck and you have set this skill/shit....
... your opponent has still 1 extra card plus the all advantages of this change. xD
In all cases, this isn't a skill anymore, so remove it. Stop.
Instead... now it's worse.
It's a clumsy attempt to put a piece in the hole.
Paywall is the only thing Konami has in his mind.
Been trying to get Last Gamble with Joey for forever, but I switched to Tea for like a day to level her up and get the level 25 reward... This stupid thing drops like 3 duels in. Probably one of the best skills in the game so I'm not complaining, but man the drop rates are funny in this game.
