Those were all the official rulings, but Jimmy jumped in and answered more of the community’s questions, right there on Facebook.
I know this question is near and dear to @ccm00007’s heart:
Wallop: Basic Action Card
This question is relevant because the text is a reprint of Flying Hammer, from The Mighty Thor (TMT) set, which is rotating out of Modern on May 1, 2020, but has a different title. So it’s not strictly a reprint, but has the same collector’s number as Flying Hammer. Jimmy conclusively says the numbering is an error, and Wallop is Modern Legal. Thanks Jimmy! And watch out, God Catcher!
