As we all know, there are cards that would never, ever make into ELO. Which ones do you think are the most overpowered? I'm thinking either Graksmxxt, Jackie Cr or DJ Korr Cr.
Graksmxxt because he's one of the two most powerful DRs in the game who can also negate cards just through brute strength. Just look at Nistarok, a less powerful 5* card that still isn't too shabby.
Jackie deserves to be a 5*. Seriously. The staff must have screwed up when they made her. Only four 4* cards in the game have 6 base damage combined with 7 base power (Wee Lee, Yayoi, Beef, Carter), but Jackie takes it to another level with EIGHT power and SOA as well.
DJ Korr is good at everything, simply put. Even without the Junkz bonus, I think a deck consisting only of 8 copies of him would be extremely powerful.
