Hello Noa. I am very good at the moment. How are you?
It's funny, I was just about to message you because I managed to get the Battle Tree Multi Battle Stamp for winning 50 battles in a row. :)
I used my Charizard Blaze which I hatched with perfect IVs and a Timid Nature. I gave him Charizardite Y (Not a fan of Charizard X) and he had the moves Flamethrower, Solar Beam, Dragon Pulse and Ancient Power. I had Life Orb Garchomp as well. My Multi partner was Cynthia who used Mega Lucario and her own Garchomp. I had no idea Charizard Y was so good. :D. Both me and Cynthia having Garchomp might be a bit cheap admittedly but Multi's seems like the hardest to get 50 on as it is so hard to scout a trainer with the right Pokemon. Luckily Cynthia has a great team.
In Battle 50 Red brought his own Charizard Y and Blue brought Mega Pidgeot. Four Megas on the field at once:) Annoyingly I forgot to record it. I've just got singles to do at some point now.
I hatched a Shiny Totodile in Crystal too. :) How have you been?
