About the Pokemon That Can Enter

• You can only enter with pokemon that can be obtained through normal play in Pocket Monsters XY, those who have been hatched from eggs, those you've obtained from an in-game trade, and those that have been distributed officially.
• You cannot use pokemon that have been transferred from Pocket Monsters Black, White, Black 2, or White 2 using the Pokemon Bank application as-is.

Left:  Your pokemon must be a native of the Kalos Region. Right:  That therefore means that the super awesome Ononokusu you transferred in from your copy of Black, for example, cannot enter.  Its Kalos-born children, on the other hand...

• You cannot use any pokemon who know attacks through any method other than:
• Learning through Leveling Up
• Learning from a TM / HM
• Learning after hatching from an egg
• Learning from an in-game Move Tutor
• Any distributed pokemon who knows a move it cannot normally learn

Determining the Winner
