Welcome to the game & the forums! 4* Katherine is a really good 4* knockback card, by the way.
Make sure to read over the Information & Policies global sticky (also listed in my signature) to familiarize yourself with our rules and some of the threads we have to offer.
Other than that, hope you enjoy the forums, and if you have any questions, always feel free to ask.
