I need help and would appreciate a discussion on deciding on whether or not to pull for wit cb or spd maru.
Currently i have 61800 carats and about 30 support tickets at the end of aries cup, and I am planning to save for tachyon + light halo. I am also dolphin, i spend on the daily carat and anniversary deals.
Oshis:
Oguri (I ran her every CM),
Digitan, Tamamo, Machan. (I run these whenever they are viable, idk much about machan though)
Current notable SSR MLBs:
Spd Fuku, wit FineMo, Spd Kblack, Power pasa, Spd Kawakami.
I don't really play fronts or ends, just depends on the oshi. I only play ends if its goldship game CM and only fronts if its sprint RNG fiesta.
My questions:
- Which one lasts longer? I heard spd maruzen lasts longer and is more general, but I don't have seiun, kitasan black, or vbourbun, so I'm not sure if its worth it.
I heard wit CB falls off a lot faster.
- Which one is better as a generalist card?
Spd maru gives groundwork and PTO (decent for pace/lates) but CB does give Tail held high. I'm not sure which gives better stats.
- In meta decks of upcoming trailblazer, grandlive and so on, does wit cb gets used more for my oshis? Or spd maruzen?
Apologizes if this is a long post, tldr I need some help from veterans on which one is better for my situation.
