Soul Buster

Soul Buster is definitely a shorter and less detailed alternative of Fate/Stay night. The start off of both anime are different, but the basic concept of the two involves teenagers playing a game and putting their life on the line for the card that they picked from their dream world. Essentially, there are other players who also chose a card and they hunt each other for the card they have to achieve whatever goal is placed for them. 

Heroes of old get summoned to fight each other for their masters to achieve a goal. 

The start off of both anime are different, but the basic concept of the two involves teenagers playing a game and putting their life on the line. While both involves having a card, Lostorage involves players gaining and losing coins that would effect their memory. If a person loses all their coins in the game, their avatar would take over their body and they would lose their memories. However, if the player gained all 5 coins, then they have the option to choose a memory they would like to change.  

Zhen Hun Jie and Soul Buster contain people fighing for peace and justice using historical figures, ghosts, and ancient beings. They both have an interesting art style, not to mention plenty of action. 

Both anime originate from a card game. The concept is the same summoner-summoned relationship where the male MC doesnt know much about the new world he has stepped in. Both male MC and his summon(girl) fight against other summoners for their own reasons, but they also gain some friends/companions along the way. 

Both have almost similar persentation technique especially with that ink splatter stuff
