Resources for an Old Rejoining Player

Hi All,
I started Yugioh 23ish years ago not long after Legacy of Darkness was released. I fell in love with the game and played through my 20s. I stopped during the Pendulum era as I just did not care for the mechanic, but I’ve always followed the game in the background (I know very little about the Link mechanic).

I’ve been out so long that I am not sure what the best websites and other resources are right now for a player thinking of getting back into the game (both collecting and playing). Any links or advice would be great.
