>>26473572they could improve the connectivity experience with different battle styles, maybe making them available only for a certain amount of time,for example, a "megabattle" mode where you can use more than 1 megastone, the inverse battle, horde vs horde, etc.
If the sync thing is not an only anime thing, i guess it could be some sort of "all in" strategy, you bet your win on the pokemon you synch with, because if he faints, you faint too and lose the battle, even if your whole party is still at full health
