Older codes for Mega Stones such as Mewtwonite X and Mewtwonite Y from March still work, allowing newer players and everyone else access these otherwise rare items. These Mega Stones, along with stones for many Mega Evolution-capable Pokemon can only be found in Sun and Moon through download codes. The other current Mystery Gift, a set of stones including Diancite, Galladite, Gardevoirite and Lopunnite, can be redeemed through a universal code from the Pokemon website.
