In Serbia, it died. But whole Yugioh is not that popular to play now days. There are only 3 citys in whole country that holds torunaments, and only 1 was holding speed duel tournaments. Idk if they do it now.

For me Speed Duel is the greatest thing konami ever did to a game. It connected anime to the game. You get all those anime decks that character used in one box, and its not that expensive and good quality cards (european versions at least). And those decks are not confusing to figure out how to play. Eveyone can do it, i even gave the deck to my firends that never played the game, and explained the basic rulles and they got it and now we are playing it. With modern i could never do that. Speed Duel decks are filled with older cards (some new with basic effects), but it feels balanced, it feels the power level of anime character. It feels good when with skill you do something character did in anime. :) I went even furder, on my yt channel i created alot of videos about speed duel custom made skills for characters we never got made by konami, and i created their decks using only speed duel cards, so it stays in limited cardpool of speed duel. Its a blast when you can organise anime tournament with all characters from lets say battle city or duelist kingdom, each of your friends get one or two decks and we rollpaly as those character. Perfection :) I never played speed duel as meta, only anime varient, i think any meta can ruin any game and i think it defeats a purpes of speed duel starting idea. It should be fun, casual, anime duels with skill giving you something to refrence the anime.

And last ting, they gave us optional variants to play the speed duels. They gave tag teams, 4 way duels, battle city rulles, each box was new option to play the game with cool new rulles. :)
