That message doesn't mean your prompt was bad (there's a different error for that), it means it thinks the image it generated had banned content. False alarms are pretty common IME but usually you can try again with the same prompt and it will work as long as the prompt isn't too likely to create something that looks like violence/sexual content/etc. for whatever reason.
Yup that's actually a tradeoff you have to consider in the game, putting more power into the engines speeds up how long it takes to make an FTL jump. So if you don't think you can beat the ship you're fighting, it can make sense to put all power into the engines to try and jump away before they destroy your ship. Turning off life support still leaves you with the air currently in the ship which lasts for some amount of time depending on how big your ship is/how many crew members you have/how many hull breaches, open airlocks, or fires there are.
I always appreciate how the game FTL made "diverting power from life support" make sense. You don't do it when your shield generators are damaged, you do it when your reactor is too damaged to output enough power for both shields and life support.
Crystal either needed to be cheap enough to enable combos or be a target for an anthem effect since she decreases the number of matches where you wouldn't draw your anthem. Putting her in surfer range seems great.
Shanna at 3 lets you do Kazaar > Blue Marvel > Mystique + Shanna which might be good. Shanna + three 1-drops might be an decent T6 option too. Probably playable but she's been bad so long that people probably won't give her a chance unless they overbuff her and roll her back like Enchantress.
People thought they would be worth something? I thought we were all leaving them in their boxes because it's the only way to keep them from falling over.
