Torchic and Meloetta Advance! Match 23: No doubt: Mega Lucario. Maybe if it was Mega Mawile, but no way in its regular form.
Match 24: I'm also going to have to go with Blastoise for nostalgia sake (not really because I nominated it). It Mega Gardevior was Shiny then yes, but in its regular form, no way jose.
