Decks whose playstyle/strategy has changed the most over time?

As someone who didn't play the game competitively until a few years ago, I was surprised to learn that Superheavy Samurai began its life as a "hit really hard" deck focused on dominating the Battle Phase and beating over opposing monsters, with its most recent competitive heyday being as a long combo deck that seeks to set up an unbreakable turn one board. So, what are some other examples of decks which have had a similar trajectory of their play style drastically shifting with the passage of time and new support?
