I had a deck like that back in the 2000s. If I got the right four cards, I could end the game in a single turn.
It was based on removing cycling costs, having fighter cards that could be cycled into the graveyard for mana, and dealing X damage for each fighter in the graveyard, or managing on the board.
The first and only time I played Magic the Gathering in a public gaming forum the guy I played against stacked the entire deck with Fireballs and mana. It was so boring I just never bothered to play in those public groups again. Better playing with friends and family who enjoyed playing the game rather than looking for instant easy wins.
That reminds me of the first time I played Yahtzee . I was coming in completely blind. She said she’d show me how to play then said exactly nothing and I had to guess how to play.
She also “taught” me the card game spades the same way.
@mrlovenstein is there on the image. It’s brutally pale text on white background so I wouldn’t be surprised if it doesn’t even render on some screens but that’s on the author.
