I don't know what world you're in, but you may want to talk to AtaguS, I know she's in a spire-loving fellowship that gets gold just about every week. Anyway, if you're on her world it's worth an ask.
If you're on Sinya Arda, my world, then you could join Thornwood. We've been getting silver just about every week and we have some really dedicated players and could use more. I've only been to the top of the spire once, but I normally get silver. We do have two "push tourneys," (steel and elixir) in which we get 10 chests, but they are about a month apart. I think the AM wants to increase the minimum to 400 points on the push tourneys, but you don't have to play any other tourneys if you don't want to. The spire we do every week.
At any rate, good luck on your search!
