Overall - This anime has it's own unique style. Not like Yu-Gi-Oh , Duel Masters, Beyblade at all! I find the game easy and less complex to understand, even noobs could figure it out! xD Anyways, the drawings fit my taste, I don't know about you guys, but I'm not a fan of super old anime drawings. What I like most of all is that it seems like a relaxing anime, even though it's about a card game, it has a bit of Slice of Life, which not every card game anime has.
Storyline - So far it's great! I like how it keeps you captivated because it sure makes me want Friday! This anime gets me captivated to play the card game sooo mucho and it's relatively simple and clean. Not sure what you think about it though! :3
Character - I love how the characters develop and evolve over time, especially Aichi. Even though he's not the best, he still tries his hardest to face his rival. Unlike how other animes, which the main character is a super duper pro at it..*cough cough Yugi*. Not only that, but even though it has the usual "my parents died" background to them, even though most animes have them. But some characters don't have a clear background of all, so they make it up by showing their personalities (Kamui xD)!
Music - The music is relatively okay, in my opinion, more lively and "full of life". I like how they play them at the right time and it heightens my excitement! LIKE FRIGGIN ROLLERCOASTER!! xD Lol! I'm currently typing this as I listen to Episode 38 of Cardfight!! Vangaurd. :P
Animation - The animation suits my taste, not like those really old looking ones like the first Hunter x Hunter (I'm not saying I hate HunterxHunter!

) . It really shows how the Vanguards/ Units attack while playing epic anime music. Wouldn't you agree?! ^.^ The artwork is amazing as well, it shows detailed Units as well as characters.
***This anime shows great promise! <3 ***
