A unbelievable pokemon battle. How is this possible?

A unbelievable pokemon wi-fi battle in pokemon battle revolution. I had shedinja, kangaskhan, toxicroak, and swampert. I almost regret it picking swampert instead of a latias with soul dew or a zapdos. The other team was darkrai, mewtwo, ho-oh, and kyogre. I think the other two pokemon were dragonite and guardivor. On the first turn I flinched darkrai with the kangaskhan and took it out with x scissor. Mewtwo used aura sphere on kangaskhan. He brought out kyogre and made it rain. Second turn, shedinja used shadow sneak on mewtwo. Mewtwo used shadow ball on shedinja and it survived it with focus sash. Kyogre took out kangaskhan with water spout and shedinja was not affected. I brought out toxicroak. Third turn, Toxicroak fake out mewtwo and has the same fate as darkrai. Kyogre used water spout and my pokemon was unharmed. He brought out ho-oh. Fourth turn, Kyogre used earthquake and almost halved toxicroak HP. Shedinja used shadow sneak on ho-oh. Ho-oh took out shedinja with flamethrower. Toxicroak used poison jab on kyogre and poisoned it, but it healed itself with a lum berry. Toxicroak healed itself. I sent out swampert. Fifth turn. Toxicroak used sucker punch on Kyogre. kyogre used earthquake and made toxicroak HP fell to a quarter and swampert lost an eighth of its HP. Ho-oh used sacred fire on swampert. Swampert used surf to heal toxicroak and made ho-oh lost a third of its HP. Sixth turn, Toxicroak uses sucker punch on kyogre. Kyogre uses earthquake again and almost took out Toxicroak. Ho-oh used flamethrower on swampert. Swampert is continuing the surf attack to heal toxicroak and damage the ho- oh even more. Seventh turn, Toxicroak took out kyogre with sucker punch. Ho-oh used flamethrower on toxicroak. Swampert took out ho- oh with surf. Tell me how lucky am I. Have you had an epic battle experience like this before? The rain helped a lot. All of his pokemon had the base stat of 680. I took them out with a "weak" pokemon like shedinja. They are actually strong though.
