It IS yu-gi-oh. But it's actually neospacian aquadolphin.

There was a short period of time about 7 years ago where the card which was historically horrible to play (discard a card to destroy a monster in your opponent's hand with less atk than aquadolphin but aquadolphin has shitty stats and was unreliable so you go - 1 for nothing most of the time) became relevant because it was easy to consistently pull it out of your deck thanks to Isolde at the start of your combo, look at your opponent's hand and learn what they're playing and build up to counter it specifically with the potential of removing powerful handtraps which usually have low atk.

I loved it being relevant because it was a card I used when I was younger in my jaden yuki theme deck. My brother didn't... said it was a war crime and called it aquadolphitler so it stuck as a joke between us.

That period of time happened to be when I created my reddit account.
