Hi. I'm Jace. It is likely. In fact, I heard that at the end of the Yami Marik event. Marik will banish his evil counterpart and be unlockable. I am Jace, always happy to help.

I have been requesting Marik Ishtar in every survey that I fill out. Based on the data mining images, I think that it is very possible that we will get him. It would be hilarious if he comes out with a Gravekeeper related skill and cards that totally break the meta, causing players who claimed that he shouldn't be added to suddenly start using him and singing out praises to him. XD

Another interesting thing during at the end of the current Yami Marik event, Normal Marik will emerge and banish his counterpart and his silhouette is going to be leaked after that it will show that the event is over.
Giving also the screen of that fragment, credits always from the dataminers XOF and/or Xellos.
Also giving out the tinypic with full scenes, https://imgur.com/a/M4UQX

The dataminer XOF and Xellos showed that he can be choosed on the character roulette (the one where you can select the character you want to play as).
So yeah he's going to be playable, not only him but also all the legendary roaming characters are going to be in the future. Just be patient.
My 2 cents, this Duelist chronicles is going to unlock Pandora (Arkana) because it looks like you'll do just the 1st part of the battle city, last boss is probably going to be possessed Jonouchi, i think there's going to be the 2nd part of the battle city and during the end of that event we are going to unlock Normal Marik Ishtar as a playable character.
