Another hotfix is coming out today, this time to address the bugged interaction between Maxima Blastenheimer and C'Thun. We didn’t really want to showcase the bug earlier, but since it’s getting fixed now I think it’s okay to talk about it. For some reason, when C’thun was summoned from the deck after getting buffed even just once, it would buff itself 60 times (which is a cap), resulting in a 128/128 version of it. Since Maxima forces the minion to hit face, it would result in an instant kill.
The deck itself was actually incredibly strong… when you could pull off the combo. The problem is that you had to draw your C’thun buffer (like Beckoner of Evil) and Maxima very quickly and NOT draw your C’thun (because that was an instant-loss). In the end, the deck’s win rate hovered around 50%, which is not terrible, but it wasn’t overpowered by any means. Despite that, it was quite popular – it peaked at around 7% popularity, which means that technically tons of Wild players were exploiting a bug on the ladder (but frankly – I could see something similar being a real deck). Luckily Blizzard didn’t ban anyone for abusing the combo, which would be a really stupid mistake.
9/9 UPDATE: We’re planning to deploy a server-side hotfix later today to address a bugged interaction between C’Thun and Maxima Blastenheimer. You will not need to download anything to receive this update.
