I can’t see how they could keep cards as oGCD’s and reduce the APM in the burst because they could never realistically tune the cards in such a way that dumping in the burst window isn’t optimal, they could remove the second charge on draw but APM of AST was still high in the burst window of ShB after they changed sleeve draw

The only thing you could do is gut auxiliary damage options like star and minor arcana so your entire burst window basically just becomes cards, even then it’s still debatable if it would fix the problem
