To increase in leagues:

All you gotta do is win matches to win up to 25 trophies. The total amount depends on how well you win a match, which you got to score around +200 points than the other players to get the full reward. But losing a match causes you to lose up to 22 trophies. But if you lose by below 150 or so points, you'll gain 22 or less trophies. But the only mode that you'll gain less trophies is in Co-op survival, which the maximum amount you can gain is 22 trophies. But which in my opinion is the best mode to farm trophies (think again, this is the best mode to farm most of everything). But although you cannot gain trophies in the Campaign or Arena modes.

And whenever you gain a league, you will gain 2 more weapon skins, a player skin, and a hat. Everything you gain in a league you'll have to buy, but although Rilisoft we're generous enough to make everything cost coins (but the only thing that costs gems is the Secret Forces Rifle golden skin which costs 105 gems on sale).

That pretty much covers it.
