Cardfight!! Vanguard

Both Yugioh and Cardfight Vanguard emphasizes the game of card play in terms of its concept. The characters from both series are skilled duelists/players that engages against others using their skill, intellect, and strategy in order to win. Throughout both series, the main male protagonist improves their skill through experience and watching others. They also are caring towards their friends and often tries to help out in the best way possible. Both series' main protagonist also has a rival (although present differently). Along with that, they also have their own 'signature cards' that are noticeable throughout the series. Cardfight Vanguard does emphasis more on team play but both series deals with strategies to outwit opponents and respond accordingly.  read more 

Both are Card Games... Both are really fun to play in Real Life Both series have a timid boy playing card game but in Yu-Gi-Oh, main character has an alter ego, as for Vanguard he has his Main Card his "Avatar"  

Both of them are Trading Card Game (TCG) themed Animes. They have some of the same concepts aswell. Like, Friendship will rule it all, Like most of the Shonens, Hehe. But if you Like that kind of Anime ''Friendship'', Then you will be served. They are both a little ''Kiddish'', So don't be surprised, But they're still enjoyable. :) And also, If you're willing to learn how to play the Trading Card Game assosiated with the Anime, It a very great source. You can learn how to play (The Basics) with the Anime. Which I certainly enjoyed. Hope you Liked. :) 

Both are focused around card themed monster fighting games and both have a shy guy who has to step up to save the day with the power of the cards in his hands.  

Both are Shounen Card Game Anime with a ton of characters, and a mixture of good and suddenly-popping-up bad art, with crazy hair too! Not to mention, both are for kids. Cardfight!! Vanguard however pays more attention to the story, with characters affected a lot by their pasts and whatnot, more emotion, more..girliness. Cardfight!! Vanguard also has a lot more of an Anime feel to it to the extent of a slightly "moe" main character, a "Kuudere", "Dandere" and later arriving "Tsundere" character included, better art too. All in all, Cardfight!! Vanguard is recommended for anyone who likes Anime like Duel Masters, especially if you're looking for a slightly more mature take on the Card game Anime.  read more 

Both are about dueling to win. Both are about summoning monsters with cards. Both are about friendship and trust. Both are about the heart of the cards. What heart of the cards means is believe in the heart of the cards, the cards will listen to you and you will draw the right card to win. Winning is hard, but winning without the heart of the cards is a Big No No. 

The card game both animes revolve around are by the same company Bushiroad, so as you can imagine they're akin in style and rules. But that's just in hindsight. The writing is similar in that Vanguard and Buddyfight enjoy breaking cliché tropes in the best possible way. Though while Vanguard does this using its story/plot, Buddyfight does this using its characters/their relations which results in you being a lot more invested in these characters than you thought you could be for a show called 'Buddyfight.' 

Both series start off at a small shop that sells a popular game in which the main characters meet and form a team after realizing they share a passion for the game. 

Both are team-tournament themed series, and have one character of main team leaving the group, and other taking an dark version of his main deck/beyblade. 

For the obvious part, both are about card games. Also, the characters develop in quite a same manner as protagonists both suck at first and are getting looked down at but develop as the series goes on. Both series also have ridiculously strong good guys that won't give a damn about other things than their own ideals.
