Champion Award

About
For getting the Champion Rank, Poe is giving them a temporary prize as a reward for their success. As a prize, he gives them the Mewtwonite Y. But when tournaments are released again, it's back to a tournament prize.

How do you get the Champion Rank?
You gain the champion rank by leveling up all Pokémon (including shinies, but not including Meowth, Deino, or Axew) to Level 100. In the Massive Update, this rank will be easier to get due to shinies already being Level 100 when you get them.

Trivia

 * Strangely, there is Mewtwonite Y, but no Mewtwonite X.
 * Champions also gain a yellow nametag above them.
