You get the same silver by selling as you do for "using" silver bags.
Also didn't realize that some people don't use the "sell" button on the bottom right of the backpack either.

Get an autoclicker (either use a program or buy a mouse with programmable macros, I rock a razer deathadder).
One click on konso ='s 8 attacks. 2.1
Autoclicker for Janken -
There's a small overlap on the "paper" option in janken and the start janken button.
By using the autoclicker on that spot you can utilize auto janken w/o being vip. 2.2
Autoclicker for Reiatsu -
Pretty self explanatory.

By Clicking "Select Again" when you're waiting for some slowass in campaign (usually me just saiyain).
Then reselecting the same camp you can force prepare the problem child.
(This works as long as they are autoprepared).
As time savers go I think you might find my home bot useful: http://forums.gogames.me/thread-18396-1-1.html
Not really sure if it still works though, havent tested or updated in a while.
