Well first of all, those other aliens are big and strong and think that hitting and fighting is the only way to win, but holy shit are they dumb as a box of fucking stupid things and they are primitive as hell (even though they have mastered interstellar travel, ignore the paradoxes here this is just a SHL point task so relax). What we will do is simply out smart them. They'll come flying in and try a big check, we will just use our alien allies' special projection guns to make the other aliens think they're hitting a player when really there's nothing there. They'll go careening into the boards and possibly injure themselves. Then we will go straight to the other end of the ice and juke the shit out of the massive alien goalie and make them look stupid. It's probably going to cause an intergalactic war that will either leave humanity extinct or enslaved, but at this point who really gives a shit?
