how can i win- conquest

how can my team of trophy range 1500-600 win against people with 3000-2000 trophies?

load up with troops before going out. pay attention to the offense/defense factors (stats) for a given tile. If you are at an offensive advantage and have a lot of members of your team as backup, you might be able to get away by winning with sheer numbers.  However if you are grossly overpowered, it’s gonna hurt.  You won’t know til you try though, right? ?
