Hopefully you can get yours too, as one of the most anticipated Tera Raids is underway. Mew is strongly recommended, otherwise you might get something like that screenshot at the bottom...
Here was my winning Mew set, as you can see, this is clearly a support based 'mon to help all the ones that use the more conventional combo of Swords Dance and Bug-Tera Leech Life. Mewtwo's Psychic Terrain as its additional move is no chance for my Grassy Terrain. Oh, and I didn't need to Terastallize mine anyway, as my Mew would then be weak to Ice Beam.
