How to get better at 2v1 fights

So Everytime I start a fight with a kid and the scores are normally like 5-0 the kid call in teamers and soon enough, here I am doing a 2v1, I am ok in 2v1 fights but it is just once the kids uses their move on me it is over. They just take turns on killing me in the game. One uses flowing water and the other waits and uses hunter grasp after I get launched. I use garou as my character. Could someone like give me some tips for 2v1 fights because we all know teamers suck. I just want to get better at the game but I can't with 2v1 fights.
