I think Ninjew nerf won't make a difference tbh, less Hp maybe would. Hallelujah's nerf also won't make a difference since it's only strong because of the whole mystic legendary combination, it would need to be area restricted much like purify, etc. Didn't run the numbers for Satan but he'll probably still wreck havoc with the nerf, his warcry can't be countered with spells and that's also a reason why it's OP, there's not much value if you try to transmogrify or combust; it should be at least possible like with other warcries. Changes to Butters and Hyperdrive are ambiguos so not sure about those; I also don't have much experience with warboy Tweek but 2 to 4 seconds of hyperdrive, even with the cost drop, will hardly be competitive if his damage is still that low. I still have to try but that's my initial impression about it. I thought a card usage event was coming our way, oh well, boo token events?
