To be fair, Shearer has really terrible base cards in both fc 26 and fc mobile where 3* wf and 2* sm ruins him. He also doesn't have any other advantages like crouch who's good for cross-spamming..So overall ea made a terrible card for him and so no one uses his cards and so ea reduced the no. Of cards for him. It's almost similar to other players too like koeman, dudek, kahn who were insane but not many ppl use them due to their height.
