Do you know, I did not get a single shiny!!!
DS had about six, and yet we play together. Both clicked on the same Pokémon 
BaronessBomburst Shinies are completely independent and random chance. A shiny Pokemon isn’t shiny for everyone who clicks on it; it’s personal to that player.
Shinies are meant to be rare, so it’s to stop everyone going onto group chats or informing their friends that ‘the Charmander on X street is a shiny!’ and everyone rushing over.
I did get another t'tar so I'm happy about that. I evolved her in bed this morning, just as the event was ending, so I could get the special moves. Is blast burn really better than stone edge?
Fire Blast isn’t Tyrannitar’s special move; it’s a charge move for a start. Tyrannitar’s special move for Community Day was the quick move Smack Down.
Fire Blast is the worst possible charge move Tyrannitar can have, so you want to use a charge TM to get rid of it ASAP.
Tyrannitar’s best charge move paired with the special community day quick move Smack Down is Stone Edge.
