Well here it is four anime with three having a real life card game while one was already a mobile game that turned into an anime. Also vanguard and Yugioh already have their mobile game but buddyfight nah. And they all have their anime. So you know what I'm gonna do so let's get onto the review

Cardfight Vanguard:

Okay so the premise is pretty much a card game pretty much so basically I'm not gonna get too much detailed into it but first let me say the good stuff I liked about it. The anime was really good and I seen it on Youtube so basically out of my favorite characters Aichi, Kai, and Ren were probably my favorite characters mainly their decks but hey it's my opinion I shouldn't be hated unless it's a valid point. Now there is a few things I hate about it first off...there are too many clans. Like seriously in the first season you had royal palidans, shadow palidans, kagero, nova grappler, Oracle think tank, pale moon, dark irregulars, spike brothers, megacolony, etc. Then after the second season I just probably didn't wanted to think too much on how many clans there are I think the second season had a little bit of clans introduce than the other series. Also I didn't liked the fourth season...and no I'm not talking about Vanguard G I'm taking about Legion Mate. I saw a bit of the episodes and guess what I hated Legion. It was so irrelevant that if I had to compare this to other style of playing in other card games Buddyfight would be Dungeon world, for Yugioh it would be ritual cards, and Shadowverse I don't know I stopped playing the game. But back to my rant I didn't liked the reboot version of Vanguard mainly of how insane it was with new mechanics like imaginary cards, or even the season after it I stopped watching that one because I don't feel like it needs a damn flashback series. And don't get me on If I hated it it's not vanguard it's just magical girls fighting familiar characters we love or hate. Oh and I didn't mention the movie yeah they had a movie. I wasn't aware of that and the movie...wasn't bad the antagonist is another clan with the power to delete clans and a card called messiah is powerful enough to save the antagonist and was bestowed to the powerful card but as a grade zero which then Vanguard G started with. And the G was...kinda meh I didn't liked the new protagonist's haircut it was too weird the Grade 4 stride cards were cool but I forgot most of it because it was boring.

Overall I give the movie 6/10, the fourth season 2/10, the first three series 7/10, G and onwards except the reboot 4/10, and the reboot 2/10, and if gets 0/10

Buddyfight

Another card game made by the same company that made Vanguard...the protagonist isn't all that bad but with the game being different it wasn't too much of everything to view, different monsters of different worlds, monsters being used for good and bad, and the protagonist Gao Mikado was pretty cool with his first buddy Drum Bunker Dragon, I liked how he obtained different forms from different worlds, one where Gao and Drum faced their dads in a card game it was kinda funny, and the antagonist having a world that he has and the power of all different dragons. It was awesome and the same goes for 100 the antagonist looked cool and same goes for his buddy and how other characters buddy's are in design. Then there's triple D...I didn't liked Bal Dragon or the concept of impact monsters, they were my least favorite things to see, then X which replaced that happy child dragon with a tough personality dragon with a Chibi panda...cute. The new world The Chaos was one world where I was like...when Star Dragon World, and Danger World advanced so far that they're pure robots, and I like the overturn/overkill play style for different monsters...the last episodes was just a tournament arc. Then we come to Buddyfight Ace where it was filler and a small plot. All I remember is the protagonist's friend turned to the dark side? It was the boring thing to watch even with the protagonist being the child of Gao plus his impact card being a redesign of Gargantua Punisher and a dragon based on the card and having many many different G. Evo forms

Overall buddyfight: 7/10

Ace: 4/10

Now we come to Yugioh...oh boy and also I'm not gonna talk about Yugioh seven mainly not interested in much of the gameplay which looked like speed duel from vrains and the remove extra deck monsters and zones...pretty much it. And also you can summon a bunch of monsters in one turn (yeah yeah I know it's an abridged reference). Basically i'm not gonna talk about it that much because honestly if I do it'll kill my brain cells so here's my ratings

Duel Monsters: 4/10

Season 0: 6/10

GX: 3/10

5DS: 8/10

Zexal: 6/10

Arc-V: 7/10

Vrains: 8/10

Seven: None because i've yet to see it but even if I did from what I saw from trailers and AMVs 3/10

Now finally Shadowverse....honestly I think the main protagonist is kinda a bit op but then again I shouldn't argue because in almost if not ALL card game anime the protagonists pulls off some bullshit trump card. But the game is pretty much like this basically there are different craft (think of different type of worlds with different powers, my favorite is Dragoncraft and their overflow ability where by having 7 or more ability points basically you gain extra effects from your cards. For example this card:

Dragonguard with 5 attacks and 6 defense with the ability to have ward as long as you have overflow active. Basically Ward is like this: No monsters can attack the leader or any other monsters unless you or the opponent take care of the ward units. So yeah it's a pain but like magic the gathering and Yugioh you have some spell cards but this game allows you to evolve your monsters. Like this

Some monsters gain additional effects though you can only do this three times per game. So basically you should choose carefully. There's also forestcraft, swordscraft, portalcraft, shadow, blood, heaven, rune, and portalcraft. Basically if you ask me what I would choose Dragoncraft for because I am a weeb for dragons in Yugioh. I think forestcraft might be good for others as there main abilities revolves around the amount of cards you play, the more the merrier but remember you are limited by the amount of play points. And there is blood craft basically imagine vampires and undead (In Yugioh imagine the zombie type monsters) and their main gimmick is they have Vengeance mode where if you (or if the opponent plays bloodcraft) have ten or less defense it activates pretty much imagine Dragoncraft only it's way more risky in my opinion as you have to watch out for some god damn power monster with higher than 10 attack points. But enough of me explaining the game overall the anime I give it 7/10. 

Well guys hope you enjoy these reviews now if you need me i'll be in my den sorry for a long response from my stories school work and all that. Hopefully I can finish some of my main stories.
