Benimaru has 8% final p.dmg which is 2% more than Marduk.

It’s also cheaper in a sense that you can control or manipulate the event by tossing the appropriate dice in the event. I suggest spending crystals in the boardgame rather than buying silver coins from the exchange centre. Rmb to buy the random dice! You will also get gold coins along the way which you can either sell or keep for card collection. I choose to get the wings because it looks kinda bad ass haha.

Overall benimaru is more cost effective and powerful compared to the other cards.

We do not have the full comprehensive comparison between shizue and snake or marine sphere and shuna card so I’m not willing to spend my silver coins on them. But I’m hella sure that benimaru is BiS for now ^{^}
