you and your clanmates get the amazing one time offer of being able to spend more money to win the next one

bahahhahahahahahhahaaha classic 

Hi! The reward depends on your Tier. Generally, there are some goodies for reaching certain amounts of Tournament points - these are individual for each player, so-called "Milestone Rewards."

Another group is Accessories which are given to each Clan member if your Clan wins with a considerable difference from your opponent Clan. Again, the reward depends on the Tier you are in.

Basically, you receive some stuff just for completion of your usual daily activities - that's the idea behind it. Along the way, you get more communication with your clan members

Time Zone penalty.  Most of my clan is asleep when CvC ends.  Makes it virtually impossible to counter the opposing team.  In particular, most of my clan will not even be awake to claim Clan Boss rewards before the tourney ends, so those points will be lost. 

lol this is spot on, win the cvc and they put you in a more difficult match :)

is why u need a active clan if they dont play i kick them lol we way a head :)
