I think Grudj got banned so Freaks players can not just go 6-8 pill turn 1 most of the time, and force a 50/50 favoring them. With Olga, Freaks maintains their ability to win rounds, but discourages this wild pilling to force coin-flips.
Another point may be, that Grudj is still great even without Freaks bonus. Even if you draw him alone in a half deck ( which is the kind of deck Freaks are almost always in), he still has good stats, with a nifty ability. Great for all rounds, especially 2nd or 3rd to clinch a game.
The issue is also that Greem is much more a 50-50 card than Freaks. Greem can be pilled anywhere from 0-7, depending in the mood of who's playing them, and then be backed up by very solid attack manip. Freaks don't have that luxury if they plan on winning enough games to hit a reasonable score in Elo.
Hi Olga is just like Chiara Cr please stop that elaborating stuff and comparing Skeelz and Freaks. Freaks can be SOB'd, Greem can't be stopped unless it's soa+sob or play her pill by pill because you'll get an instant 2 life.
