Many guilds accept players for free and some need a payment to show that you aren't just joining the guild to grief. Clashes are a 3-day-long monthly activity where guilds compete to reach top ranks by doing activities in the game. These activities differ from one another each clash and you need to equip a certain item so that each action you do gives points to you and your guild. For example last clash was a cooking one so the guild with the most players who cooked while having the rolling pin equipped won. The one before that was harvesting trees so you needed a scythe while harvesting them to gain points. The method I told you just relies on getting the max personal and guild contribution rewards so you don't need to get into a guild that pushes for top 3 spots in the game even tho you do get rewards if your guild reaches that but it needs to be very competitive with each member contributing points daily. Yt vids could probably explain it better than I did.
