What's the point in coming up with theories that are hyper-unrealistic? Those aren't theories, they're fantasies.
Mahad, Monster Reborn, Graceful Charity, Chaos Max and Kunai with Chain are obviously never happening. (Kunai because it's a pack card.) Probably not Waboku or Juragedo, either.
At least the guy that came up with Mokuba suggestions was in the realm of possibility.
Yes, I can totally see how "Graceful Charity is a super-unrealistic card to release into Duel Links" is a personal attack on someone... The cards have zero chance of being here. I'm not sorry for saying that, nor should I be.
