I have found that trophies are better used on stable upgrades than on memberships. Even with stable memberships the game is still slow, and is probably better played slow anyway because it gives you time to find the correct items and develop your strategies.

You can gain trophies from several sources in varying amounts:
1: Buying them with real money
2: Between 5-20 for completing arena challenges
3: Between 10-30 for Winning top 10 battle royales, which happen daily
4: 1 per win in the blood games
5: 1 per kill in blood games or arena
6: 1-5 or so occasionally in the tavern
7: 1-5 occasionally from the gauntlet
8: 1-5 from conquest on occasion if I remember correctly
9: 50-30,000 from street games in the black market
10: 20-50 for a 7 day login streak
11: 100 every 100 days of logging in, there also might be a 250 for a year of logging in but I can't recall

I might have missed a few sources, but this is the majority of them.

In summary if you play the game long enough you will get trophies. The more glads you have the faster you will get them, the more black market spins you can get, and the faster you will develop. It is very important to max out your barracks first for this reason. I hope you find this helpful, Kramer.
