How do I S-Rank Mega Mawile, Mega Glalie, Mega Ampharos, Mega Gengar, and Mega Mewtwo? I've caught every main mon and from the expert stages have most of them, the relevant ones being Lucario Absol Heatran Entei and Yveltal. Also I only have like 10000 coins left to S-Rank these 5 and then catch Mewtwo, I still have all 3 gift items.
