That game was pretty interesting and I don't want to sound mean but I wouldn't say you were being outplayed. Rather, you were playing horribly. You basically sacrificed your Giratina for no real reason and then attempted an incredibly premature Xerneas sweep despite the obvious Xerneas counter in Jirachi, which is complete Zekrom bait if you didn't go all in with Xerneas, which was basically already dead by the time you tried to save it for later. Furthermore, your handling of Dialga with Mewtwo was a waste with Ho oh still alive and well. Some of your predictions near the end were pretty decent but at that point you HAD to play your ass off because you had already squandered half of your team for no real reason. The fact that you even gave him the opportunity to miss was probably a mistake since Zekrom already pretty severely ravaged his team and Kanga did nothing that Zekrom/Ho-oh couldn't accomplish already.
