Oh and this is an extra rule at the last minute. If Groudon and Kyogre reached 40, they Primal Reverse into Primal Groudon and Primal Kyogre. Rayquaza, Latias, and Latios mega evolve at 40. All Primal Reversions and Mega Evolutions have a 2x score increase or decrease. Also if one of these Pokémon go back lower than 40, they turn back to normal.
