Oh okay. I was more wondering about like, the duels in IC are handled text wise like keeping stats on-screen and updated after every turn, but I guess that depends on the person.

Anyways one more question, what about the Synchro bosses used by people such as Yusei and the gang, or Xyz monsters such as Numbers? I know I didn't see anything in the OP about it, so unless I missed it are they free game? Or is it just best to avoid so time continuum doesn't get fucked.
